It will be very interesting to see what lessons the PLA learns from the Russian failures in Ukraine. The current PLA force structure has all off the problems the Russian military has and in addition lacks any senior officers with actual war fighting experience.
The next few years will be very telling. A major restructuring of the PLA into modern agile, joint units led by commanders with the autonomy to adapt to battlefield conditions in real time would be a very worryingly development for Taiwan.
I think the chance of that happening is low. The downside of the status quo is military senior leaders chosen for political fealty, not military competence and who will tell Xi only what he wants to hear, which is exactly how Putin vastly over committed with the Ukraine invasion.
Unfortunately either way the outlook for Taiwan is not great. The only difference is that the current PLA is unlikely to better than Russia is doing in Ukraine. However win, lose or draw Taiwan will be devastated.
