Yeah, I've been thinking lately as well, why are we doing that? I mean as a society? (I recall a phrase said by someone, that we are consciously building a future nobody wants to live in.) What exactly are we getting from that?
Ultra-rich, namely car companies owners and shareholders, will become even more rich. (Why are they doing it, by the way, don't they have enough super-cars, mansions, yachts already?)
What am I getting from it? Basic goods will become 7% cheaper? Who needs that? I am happy with current prices.
And then dozens if not hundreds of millions people worldwide will lose their jobs and even more the very means for their existence. What will be the impact on their families, communities?
I may be terribly wrong but it seems like yet another round of value extraction by a small cohort of ultra-rich from general society.
There are technologies that are genuinely useful, like space exploration, scientific projects, disease fighting, urban development, planetary computer network, and so on.
And there are "comfort gimmicks" like refined sugar (and sugary drinks), tobacco, toasters, etc. that produce effects from which people living consciously and healthy would want to get rid of. And that are propelled only by "economic factors". Which are a paperclip maximizer.
