I said cheaper. Not better. What difference does it make if it's better if only a few people can afford it. I also don't accept longer lifespans as something that is always worth pursuing.

You also didn't address my point that those technologies do nothing to solve the real problems that real people want solved. There's a strong possibility that they'll just exacerbate them.

I guess your argument could be leveled against any transformational technology, from the industrial age through to the internet (which many doubted would have any meaningful economic impact, and clearly didn't solve many of the most pressing problems of the day for humanity).
