You're almost certainly right that the Chinese can get there on their own. They have more engineers than any other country in the world and the most of the top 100 universities. I believe we're being really stupid to harp about China buying the machines like we do. As long as they can buy them eventually, they'll probably be OK with being a couple of gens behind. But, if they have to make the investment by themselves unlike anyone else in the world, they'll probably do it right and use their mass to feed their own machine and move ahead of the rest of us.
They aren't stupid. They are the longest term thinkers in the world. Even if they could make the fab work, the industry advances so fast that in just a couple of years it is no longer state of the art. There is no way to invade Taiwan and get a long term pay off on chip production. In their best dreams, it would be a boost for a few years but destroy any further chances to keep up for many decades afterwards.
I'm not saying entirely that they wouldn't invade Taiwan - just not for that reason. Quite the opposite perhaps. If we disconnect them entirely and give them no chance to keep up, then we back them into a corner. They can't hope to survive with the rest of the world advancing and them not. At that point, the argument that invading Taiwan precisely to destroy most of the world's top chip production would come into play. Setting back an enemy who is actively trying to destroy you could be a worthwhile goal.
If life begins at conception and a state bans aborting a fetus older than some age, I guess all IVF embryos are considered to have been conceived and can never be thrown away if they pass the state's abortion age. The legal definition of conception does not include implantation. So they'll have to keep them till implantation regardless of cost. To dispose of them prior would put a medical professional in prison in some of these states.
It will also allow a woman who lost her ovaries to have a child to have a child with a man or a man with no sperm to have a child with a woman. So it will be developed. Of course, it is already in process with animals. That is a big market. Once developed for humans for any reason, it will allow all of those other cases. Just the way things work. If some state then bans it, go to another.
