They have different problems that pressured water reactors and are not as applicable to applications that the military would like to use them for. So the government sponsored research labs that were running and experimenting with them stopped doing so when research funds ran out.

Add to the insane risk of investing in anything 'nuclear' and you don't have a lot of available capital. That said, the Chinese who invest in research for other reasons seem to have been working on a number of MSRs which could conceivably advance the state of the art significantly.

Oddly enough, as an American, I am looking forward to the first thing that China builds that "we" American's cannot because we lack expertise and/or technology to do so.

Or too much regulation or politics to allow.

Exactly right. The one that came in conversation waiting for the eclipse was genetic editing of fetuses to eliminate inherited disease. Setting aside the whole 'designer babies' as a distraction imagine a company that give free genetic treatment for couples seeking to avoid passing on known bad genes. When you walk that forward and look at the cost associated with treating, diagnosing, and supporting people that later get the disease, you begin to see a huge economic 'win' by giving them free genetic help early.

Why would you expect that treatment to be free?

If the cost of editing is not exorbitant (i.e. is lower than the average per-capita cost of paying for the condition being edited away), healthcare providers would be incentivized to pay for the editing to reduce their costs.

The incentives are obviously stronger in single-payer countries, but even in the US you could imagine an insurance company that competed on lower premiums conditional upon certain gene edits being applied to covered children.

On one hand, this sounds entirely economically reasonable (and even humanitarian).

On the other hand, I fear this would inevitably produce unintended consequences that would shape our society in distopian, sci-fi/horror-flavored ways.

I have no idea how it would actually shake out. Maybe I'm just being anti-intellectual here.

Given the economics, I feel pretty confident predicting that these edits will be mandatory before most people on this site die.

At least you'd probably have to pay a lot more of the bills if you chose not to have genetic problems corrected before birth.

Expect is perhaps too strong a word, the calculus would be the cost burden of providing services and treating the diseases in the uninsured to the cost of providing the genetic services at the start.

The thing is... Abortion is so much cheaper than gene editing, and it gets all the cells at once. More likely is insurance companies try to deny coverage for people with genetic conditions diagnosed before they were born. While this would not fly in todays environment, it is where the economic incentives point.

Or, as a German, too much regulation/politics to Get Shit Done.

Just look what happened to Transrapid (maglev rail). All tech and IP went off to China, and we're stuck in 1980-and-earlier carriages for anything not an ICE or regio trains.

Actually, the InterCity and EuroCity fleet was just entirely replaced.

This means the entire fleet – S, Region, InterCity, EuroCity, InterCityExpress – is now replaced, or being replaced, with modern stock.

Offtopic but this means I am totally heading back to ride the new trains :-)

Here the new stock:
