There is no permanent tech advantage to either side in this war. Only the potential for peace is permanent
Ukraine used Turkish Bayraktars, Russians got Iranian Shaheds
Russians invented cope cages, Ukrainians got them too.
Ukrainians got FPV drones, Russians got them too
Russians invented fiber-optic drones, Ukrainians got them too.
Now if the Ukrainians get assault robotic and evac robots, the Russians will get them too
One side has most of Europe backing it; the other side has most of Asia. Too many resources behind both parties for either to lose easily.
Stop the fighting. There are no winners here. Only worse-off losers.
Both Russian casualties and Ukrainian casualties have long passed the 'unsustainable' mark. Now both side are getting close to the point where either side can tap out. But Ukraine is closer to that point than Russia. Yes, Russia is losing, but Ukraine is losing harder and faster - it has less land, men, money, and munitions than Russia. It is getting attrited faster. Ukraine has the bigger job ahead of it after the war - blowing up unexploded ordanance, demining, rebuilding, repopulating.
Ukraine needs to:
(a) make an offer that the Russians can at least use as a fig leaf to concede peace.
(b) Ukraine also has a problem with a section of insubordinate rightwing soldiery that resists any peace concessions. Ship them straight to the fight. Want to disobey? Go fight then! Just don't take the rest of the country with you.
Why? So Ukrainian people can live. So its current leader can live. So the country is not at risk.
