you probably want to read over what patch wrote about Taiwan invasion scenario. What you are talking about here doesn’t make sense at all for PLA provided them have air dominance.
I did and do with great interest.
With respect to you personally, as a tech observer and popularizer, I think we can agree that we have different views on modern state of ground warfare, and warfare at large.
Maybe my views aren't a good match for what we are to expect in late 2020s, but this isn't how i see things, and to my knowledge, isn't the way staff work is performed at.
Neither from point of view of where warfare as craft stands, nor from the point of view where PLA in it's entirety - not it's advanced elements, - does.
There are advanced visions, which, at a certain pace, twisted, transform into reality. There is reality of warfare as science/art, which just doesn't quite align with vision technology world. There is economic aspect, where China changes at breathtaking pace - but this doesn't change entire nation on a whim. New ZTXs will indeed operate in parallel with type 59s in (rear, sure, but)line formations, as J-20A, apparently, just barely intersected with J-7s in last units. And then there's reality of armed forces as a social institution, where career military officers, doing their calm service some time all the way from late cultural revolution, encounter modern world.
Why would you want it to when you can have drones do the job? If you have this great information advantage and entirely attritable unmanned platform, why would you not take advantage of this?
For example, when there's not enough ready drones to disable that abrams, when you run into them in a meeting engagement/ambush (i.e. column runs into them).
First, you have to even survive the engagement, which unfolds immediately. Then, if you can't resolve action as a meeting engagement (i.e. with immediately available onboard armament), regroup, deploy and dislodge that position - enemy already achieved his goal.
Main currency in any breakthrough is time.
If you don't do meeting engagements - that's fine, but then, drones or no, it's likely to be a grinding positional fight, where opponent has time to prepare and react.
