The problem that we have is that the ruling class want to utterly remove most people on this planet from the competition of life, and convert us into serfs or slaves (as opposed to free landowners) while establishing themselves as rentier-overlords who own all property and rent it out to us in order for us to live.Human beings always insist on learning everything the fucking hard way.
My money.
There are going to be a whole lot of varables you simply cant account for, and that it will all end in tears and blood shed and when its all over western civilization will go hard traditionalist and inovation will become a dirty word once more.
They present this as a drive for "sustainability", but it's really just an attack on private property. They aren't even discreet about that part, either. They openly promote the idea of taking products and turning them into services.
What kind of world has no privacy, no private property, and mass surveillance with implanted nanotechnology? That's slavery with a smiley face on it. The chains are invisible, but they're still there.
People who are trying to bring about a system this blatantly immoral won't care about the side effects or safety issues with these technologies at all. In fact, to these Neo-Malthusian eugenicists, they're a bonus. Someone dies? Whatever. That's a win for depopulation and degrowth, and it makes more room for people with the genetics that allow them to withstand the implants with minimal side effects. These people don't give a damn about product safety.
