Nuclear power is not a trend for the future
-snip-
After the
Fukushima Daiichi disaster more than one decade ago, the world has been changing core approach to nuclear power.
Indeed, that accident accelerated the use of renewable energy as the future energy and some countries put plans to be almost 100% green in the future. New nuclear stations are planned to be build mostly in Middle East countries afaik while they should have hell of solar power!
Anyway, I don't expect anything to change in the next 20 years.
I think you both are referring to Fision... But I'm talking about
Nuclear Fusion, which is under heavy research since a lot of years and is much more clean and green than anything.
That's true. I was talking about the nuclear fission. Otherwise, I heard about this concept of fusion, not sure how far was made and when it will be widely available, need more data honestly, but having cheap and clean energy will make big oil companies digging for (mining) bitcoin and cryptocurrencies in general

For the centralization part and the attacks, I doubt it will occurs.
