To me the only question is if there's a hypothetical revolution who will end up swinging in the wind by their neck and I have no doubt many engineers working for big tech would have been in that group. There's always nice rhetoric and focused rhetoric to not make too many enemies but the people on the ground differentiate a lot less and have in every revolution.
By the time there is a revolution, i'd imagine that most engineers will have fallen to the working classes where they are technically a part of.
Again, they are not part of the capital class. They were lucky to come across a special moment in time where there was a paradigm shift bringing with it enormous wealth and the capital class did not part with some of their wealth out of charity but out of greed because they realized that in order to capture this new found fountain of wealth they needed engineers...at least for the time being.
This allowed one generation (maybe two) to live a dignified solid upper middle class life but since the beginning there has always been a push to eliminate them.
Things such as low/no code, "learn to code", bootcamps, and now AI are attempts to destroy this avenue for people to rise above anything more than just worker class.
