You probably will before Russia does, in every sense.

This sounds very reasonable and in theory maybe this is how it should be or once was.
However, I have to agree with @keas66. He was referring to the MSM (Main Stream Media) which you called "generalist media". I think your talking about CNN, MSNBC, BBC, etc. when you say "generalist"?
The MSM often went into great detail and analyst about the war, especially in the beginning. It was almost non-stop details and analysist that was often wrong. Kyiv was about to fall, Zelenskyy needs to leave the capital, Poland might be invaded, nukes are possible, Putin needs an off ramp etc. They had generals and colonels standing in front of map boards giving detailed analysis. Lots of photos of IFVs / APCs generically called tanks. Many experts and analysts giving their detailed input. At the bottom of the screen the talking head often had expert, analyst, general, colonel, SF operator etc. in their title.
But we knew they were wrong because we had this forum topic. I couldn't (still can't really) get enough of it. So I switched back and forth between six or seven MSM channels plus u-tube, twitter, internet, etc. It was (is) all very interesting. But one thing that became obvious was that the MSM was often wrong. Even when they were right they were a week or more behind actual events on the ground.
If the MSM was delivering a broad stroke first draft of the situation they were selling it as detailed expert analysis which was often wrong and out dated. In an AAR of this historical event I think it is fair / appropriate to point this out.

He's looked for a while like he was on steriods. My mom was on prednisone for the last few years of her life and it caused noticeable mood and temperament swings as her levels went up and down. If she'd had the resources, there were probably a few mornings when she would have invaded Ukraine.

China is much closer to becoming a peer space power. They have much more electronics capability, even if they don't control all the knowledge. They're the only country besides the US that has successfully landed on Mars, and they did it in a rather dramatic fashion - they skipped all the orbiters, stationary landers, and small rovers and just went straight to a full up combined orbiter+lander+big rover mission, and did it the first time out. They aren't quite caught up, but they've been launching a lot and improving their capability rapidly. On the bright side, if there were to be a conflict that probably makes them much less likely to just go shattering things into space debris because they'll have just as much to lose from an uncontrolled debris field. They're more likely to develop capability to disable specific satellites without making a mess and would be able to develop the capability for it. Russia had very little to lose by basically exploding a frag grenade in space - a few old satellites that might already be junk anyway.
And it's already a mess up there and getting worse - Starlink is just getting started and they're already producing a ton of near misses all the time (link). There are various proposals to try to collect some of the garbage, but I don't think anybody has really come up with a good technology or plan yet. But with the cost to launch a swarm of cubesats to LEO, I can imagine that even if it becomes an even higher collision risk environment, short lifetime ISR cubesat swarms could become a thing. Just launch a bunch, knowing they'll all be dead in a few months.

I'm familiar with him, and actually sat next to his former book agent on a plane a week or so before this past xmas (by dumb luck). We didn't talk about Zubrin, but I think we did talk about space.
Russia is probably 40-ish years behind in space ISR assets, much like they're behind in things like microelectronics and NVG. Most of it has the same root in the Soviet Union failing to try to copy Silicon Valley from the 70's on (and probably earlier). The USSR and later Russia were/are fine at building big things made of lots of metal that spit out fire - tanks, missiles, rockets. But without microelectronics they can't keep up with the kind of data volume that you can collect and integrate if you have relatively cheap high performance sensors and cheap, fast computers. They've been able to buy some of those things to an extent, like the Thales targeting systems, and presumably microcontrollers for various things, but they can't do the kind of mass production that makes fancy chips appallingly cheap.
I came across an article (linky here) a while ago about when the big divergence between US and USSR capability happened in space. It's by one of the space journalists who figured out the capabilities of the first KH-11 in 1977 (launched in 1976) and sat on it for a year until a spy sold the details to the Soviets. KH-11 can do about 10 cm (4 inch) resolution on the ground, and there are 5 of the latest few versions in space right now. And the NRO is giving away telescopes that size to other agencies, because they presumably have better. One of the things that the Aviation Week journalists held off on publishing even longer was the existence of a second satellite network whose sole purpose was to be able to relay images in realtime from the KH-11. So the US had realtime 10 cm resolution on the ground in 1977. Russia was still returning film capsules in 2016.
And "New Space" has changed things drastically - commercial companies can give you multiple daily revisits of any location on earth at resolutions between 20 cm and 3 m. Basically, kids in a garage in the US can make and launch cube sats cheap enough to do 3 m resolution more or less hourly. If you have several billion dollars you could do half meter resolution that often, and there's probably a commercial market for it. The stuff you need to do that is export controlled, and just about all the high res imaging companies are US based for that reason. The USG is the largest customer for those data.
Synthetic Aperture Radar (SAR) is becoming comparably cheap and there are multiple companies doing that, too. And it can see through clouds. And those companies also tend to be US based for similar reasons to the optical imagers.
There were some twitter posts early on about likely degradation of GPS over Ukraine, figured out from looking at the errors reported on ADS-B data. There was speculation that it was Russia doing it, but it seems more likely that it was the US/NATO. Ukrainians know where they are and have maps, but the Russians appear to have lousy mapping and were using some commercial GPS units, so even being able to mess them up by putting them a couple roads over from where they were supposed to be could help UA.
And that doesn't even get into the SIGINT and ELINT stuff. But three things are happening to ISR from space right now - the cost of launch is going down fast, the cost of making stuff to launch is going down fast, and the size of the electronics you need to make that stuff work is going down fast. So the west has tons of space ISR going on, both commercial and government. And Russia, well, doesn't. They have two optical satellites that are getting old and probably don't have anywhere near comparable performance to western stuff. They probably have some SIGINT and ELINT satellites, but the lack of a microelectronics base makes it likely that those are very limited in capability.
All of which leads to the Russian anti-satellite test in November. There was speculation at the time that it was intended to produce a ton of debris to blind the west so that they could do exactly what they did. They did succeed in making a mess, but didn't take out any significant satellites. And even if they took out a few, there are so many that they wouldn't be likely get them all, and the three letter agencies tend to keep some sitting around on the ground for launch-on-demand, so they could launch above the debris if they needed to.
edit: here's where Russia is with ELINT/SIGINT satellites and SAR, which is basicaly nowhere:

Watch for a thread from Trent on poor maintenance of seals on Russian tanks. Rubber does go bad over time and seals need to be replaced. Fancy synthetics can last much longer. Could water have leaked into the engine intakes all at the same rate so they all got the same distance in the water? You'd think if the engine were running ok, you could be sitting in a lot of water leaking in and collecting at the bottom of the tank and still get across. It might suck, and you might have a lot to clean later, but you'd have a decent chance of getting across.

Found this site (link) that has all the stuff you have to prep to do a crossing deeper than 1.3 m but less than 1.8 m, so you can keep the hatch open and don't need snorkels. There's a lot of stuff to do, and if they weren't well trained might have all missed the same thing or had the same thing fail (exhaust valves letting water in?)

So the US had realtime 10 cm resolution on the ground in 1977. Russia was still returning film capsules in 2016.
And "New Space" has changed things drastically - commercial companies can give you multiple daily revisits of any location on earth at resolutions between 20 cm and 3 m. Basically, kids in a garage in the US can make and launch cube sats cheap enough to do 3 m resolution more or less hourly. If you have several billion dollars you could do half meter resolution that often, and there's probably a commercial market for it. The stuff you need to do that is export controlled, and just about all the high res imaging companies are US based for that reason. The USG is the largest customer for those data.
Synthetic Aperture Radar (SAR) is becoming comparably cheap and there are multiple companies doing that, too. And it can see through clouds. And those companies also tend to be US based for similar reasons to the optical imagers.
There were some twitter posts early on about likely degradation of GPS over Ukraine, figured out from looking at the errors reported on ADS-B data. There was speculation that it was Russia doing it, but it seems more likely that it was the US/NATO. Ukrainians know where they are and have maps, but the Russians appear to have lousy mapping and were using some commercial GPS units, so even being able to mess them up by putting them a couple roads over from where they were supposed to be could help UA.
And that doesn't even get into the SIGINT and ELINT stuff. But three things are happening to ISR from space right now - the cost of launch is going down fast, the cost of making stuff to launch is going down fast, and the size of the electronics you need to make that stuff work is going down fast. So the west has tons of space ISR going on, both commercial and government. And Russia, well, doesn't. They have two optical satellites that are getting old and probably don't have anywhere near comparable performance to western stuff. They probably have some SIGINT and ELINT satellites, but the lack of a microelectronics base makes it likely that those are very limited in capability.
All of which leads to the Russian anti-satellite test in November. There was speculation at the time that it was intended to produce a ton of debris to blind the west so that they could do exactly what they did. They did succeed in making a mess, but didn't take out any significant satellites. And even if they took out a few, there are so many that they wouldn't be likely get them all, and the three letter agencies tend to keep some sitting around on the ground for launch-on-demand, so they could launch above the debris if they needed to.
edit: here's where Russia is with ELINT/SIGINT satellites and SAR, which is basicaly nowhere:

I'm familiar with him, and actually sat next to his former book agent on a plane a week or so before this past xmas (by dumb luck). We didn't talk about Zubrin, but I think we did talk about space.
Russia is probably 40-ish years behind in space ISR assets, much like they're behind in things like microelectronics and NVG. Most of it has the same root in the Soviet Union failing to try to copy Silicon Valley from the 70's on (and probably earlier). The USSR and later Russia were/are fine at building big things made of lots of metal that spit out fire - tanks, missiles, rockets. But without microelectronics they can't keep up with the kind of data volume that you can collect and integrate if you have relatively cheap high performance sensors and cheap, fast computers. They've been able to buy some of those things to an extent, like the Thales targeting systems, and presumably microcontrollers for various things, but they can't do the kind of mass production that makes fancy chips appallingly cheap.
I came across an article (linky here) a while ago about when the big divergence between US and USSR capability happened in space. It's by one of the space journalists who figured out the capabilities of the first KH-11 in 1977 (launched in 1976) and sat on it for a year until a spy sold the details to the Soviets. KH-11 can do about 10 cm (4 inch) resolution on the ground, and there are 5 of the latest few versions in space right now. And the NRO is giving away telescopes that size to other agencies, because they presumably have better.

Polish scholar evaluates the overall operation and the debacle at Bilohorivka, from RU sources, with maps. Translated below....
How was it under #Bilohorivka? Two days ago, you could read an excerpt from the action thanks to @ kms_d4k
The Russians are shocked by the development of accidents and the losses. Today you can see the full version of the events from the Russian point of view
2. The entire operation lasted from May 2 to 10, but battles with the Russian survivors are still ongoing. A massive forcing operation that is not over yet
3. On May 2-3, Russian forces crossed Seversky Donets near Shipilovka [break 1].
After the crossing, the Russian army joined the battle with the garrison of the settlement. There were no troops ready to fight in Shipilovka, the garrison withdrew towards Privolye.
4. Russian units dispersed in small groups around the area. The fighting started near Novodruzhsk, on the outskirts of Privolye and #Bilohorivka. Until the occupation of Shipilovka, a relatively small calculation of forces and resources was involved, which was less than half the BTG
5. On May 4, the bridgehead near Shipilovka [crossing 1] was lost. It happened most likely due to the underestimation of enemy forces in the surrounding settlements. A full-fledged battalion of the Armed Forces of Ukraine was stationed in Privolye, which was soon reinforced by Novodrużesk and #Lysychansk.
6. On the night of May 4-5 and in the afternoon of May 5, on the left bank of the Donets Siewierski from Serebrianka to Privolye, massive artillery preparations began [yellow arrows]. According to reports from local chats, the coast and the vicinity of Shipilovka "were littered with the corpses of the Armed Forces of Ukraine".
7. On May 5, Russian forces crossed Donets near Serebrianka [crossing 2].
It was not possible to get a bridgehead on the opposite bank: the combat-ready units from Siewiersk were transferred to Serebrianka.
8. Seversk itself included newly rotated units of the Armed Forces of Ukraine from #Sieverodonetsk, which were replaced by territorial defense units and national battalions. Artillery preparations at the positions of the #Ukraina Armed Forces continued for a few more days.
9. On 7-8 May, Russian troops crossed Donets Siewierski, near #Bilohorivka.
The Russian troops managed to occupy the dominant hills near the coast (the so-called Shipilovsky Mountains) and to capture the outskirts of Belogorovka along Pervomajska Street.
10. Subsequently, the Armed Forces of the Russian Federation met fierce resistance from Ukrainian units. The fortified area of the #Ukraine Armed Forces was in a residential area and near the Cretaceous quarry
11. On May 8, the Allied forces began a full-fledged pontoon crossing [crossing 3] across Donets Seversky near #Bilohorivka to introduce armored vehicles into the battle. Ukrainian artillery began to operate along the passages
12. Before the failure of the first pontoon, several pieces of equipment were transferred to the opposite shore. Russian forces continued their offensive on #Bilohorivka, where the Ukrainians transferred their reserves from Siewiersk.
At Sipiłowka, the Ukrainian troops were again thrown back to Privolye
13. On May 9, the pontoon crossing at #Bilohorivka [crossing 4] was restored. The transfer of up to 100 units of equipment began to the occupied bridgehead.
14. The approximate plan was to consolidate the success in #Bilohorivka and Shipilovka from Privolye, as well as prepare for the storming of Seversk.
15. For an unknown reason, the equipment was not put into combat and was left near the headland on the other side of the Shipilov Hills. Presumably, on the night of May 10, the Armed Forces of #Ukraine conducted air reconnaissance and discovered a huge accumulation of equipment near the crossing.
16. Ukr. artillery launched a massive artillery attack on the outskirts of the Shipilov Hills. Most of the equipment moved to the eastern shore of the Dońca Siewierski (with the exception of the BTG equipment used in the battles of Shipilovka and #Bilohorivka) was disabled.
17. On May 11-12, Russian troops from #Kreminna and #Rubizhne were handed over to the assault on Privolye by the Russian forces remaining on the west bank of the river. Fighting in this area continues.
...
4. A complicated situation under #Bilohorivka. Some of the Russian troops managed to survive (a lot of them had to be crossed) and are attacking the NE along #SiverskyiDonets. The Russians tried to evacuate them or send reinforcements, but the next crossing was destroyed by the Ukrainians.
5. Ros. They are gathering crossing equipment on the #SiverskyiDonets bend and will cross the river from the side of the captured #Rubizhne to connect with the unit from #Bilohorivka and go to the rear of the #Lysychansk defense. It is a very difficult place to defend due to possible attacks from 3 sides .

You could probably have autonomous truck-hunting drones by tuesday of next week if you're willing to accept some constraints on their deployment, like they may not be all that picky so you have to constrain them to areas with no friendlies.
And your point defense of the artillery and its train will have to not only be able to spot and eliminate drones from the sky, but probably also detonate incoming arty high enough that all the explosive energy behind the shrapnel is spent before it gets to the ground.

It does look like it was used more for evacuation than getting BTGs across - the mud tracks on the UKR side indicate vehicles were going from that bank to the RUS side. If vehicles were coming out of the water more than off the bank, they'd probably be dripping enough to rinse those better. Also, that bank on the RUS side looks like the steepest of the three attempted points. The had to put that pair of ramps there to keep from chewing up the bank too much and may have needed to do some winching to get up it anyway if it was really muddy.
