Already India and chine have had working ones for many years. It’s not speculative and I recommend you to research the tech. It’s unfortunately not very present in western nuclear energy debates. Could be a political reason but that’s just a dirty guess
The problem with these arguments and the focus of debates is that they are based on nuclear energy from uranium, not thorium. Thorium is ubiquitous in nature, power centers are much easier to set up and can be small and the waste, while initially (a bit) more radioactive than uranium waste, loses it’s radiation level much faster

Wealth predator. It has more of that negative connotation it deserves
In Europe we have PSD2 but I dunno if it’s enough to create a full app
Uranium is a much scarer source compared to thorium. Uranium can also be used to create nuclear weapons, that’s why other countries have difficulties using the tech because foreign powers are afraid of these consequences
