Futurology

Tech can't solve those problems, because they're not technological problems. There are intensive studies on them and they never prove definitely feasible. For example, 3D printing is not reliable and not scalable. Robotics require very precise and stable conditions, a simple breeze that would just have workers using a jacket, completely stops a robot. Same with container homes, prefab houses, etc. they only seem to work under controlled conditions but fail in real life settings. These tech startups don't want to solve any real problem, they want money, to sell out and retire early.

We already have all the technology we need to provide full housing, medical care and education to all humans on earth. But we won't because that doesn't fill the shareholders pockets.
