Outside of academia, new technology is only developed to replace jobs, or to sell commodities. A business always has incentive to do away with workers when a machine can do their job cheaper. And those machines, aren't designed to make the workers jobs easier. If regulations force safety on companies it can protect workers that way, but only to the bare minimum. If anything, machines have wrecked our bodies and minds. I'm not even convinced that commodity consumption isnt a way to shackle workers to even more machines.
