Honestly yeah this is kind of a game over for the hopes of revolution type tech if taken far enough in terms of interfacing with things like memory if they have enough time for mass deployment. You could instantly detect anti-capitalist thought and report it or detonate the chip, perhaps even program and indoctrinate people repeatedly depriving them of free will. If it gets to the point the capitalists can do that we're fucked, it's just over for us. That plus AI plus automation and robotics is a bad mix. Under socialism it would of course be amazing and to great benefit but I deeply fear what happens if this tech gets advanced enough to more than read but also write which seems inevitable. At that point they just pressure the population into them, especially those most likely to revolt while allowing top white collar workers to opt out for the time being.

I don't know, no good answer, if China doesn't do this work someone else will but I almost think it's the type of thing that should be done in absolute secret by security vetted individuals. There's no way the west allows Chinese brain chips anywhere near us so we'll never see the benefit anyways.
