I like it, because the world is not going to reduce its suicidal dependency on fossil fuels with just renewable energy (solar, wind, tidal...). Safe(r) and cheaper nuclear reactors could bridge the gap.
But, I do wish the development of thorium based nuclear reactors would be accelerated, so we can stop with the primarily uranium nuclear reactors that have the capacity of dual use for helping to make nuclear weapons (which the world has enough of). Additionally, thorium is safer.
Nuclear energy isn't scalable in either the long or short term. The renewable energy route is faster than wishing for thorium based technology.
Most countries are just not in a position to scale up their nuclear industry, and extremely reluctant to do so. It is a lot harder to get rid of all that industry when you are done with it, than with any fossil based plants built to bridge the gap. All of that leaves out considerations like a neighbor invading your country and trying to blow up your shit.
Thorium isn't "pie in the sky", it's very doable (https://spectrum.ieee.org/china-closing-in-on-thorium-nuclea...). The issue was that thorium was abandoned by the U.S. and other countries, because uranium nuclear reactors (despite their greater dangers) have dual use, and can be used for creating nuclear weapons. Other countries followed the U.S. example, thus we must live with these greater dangers. If not from nuclear accidents or sabotage (or stray bullets), from unfriendly countries having disguised nuclear weapon production programs.
Plain and simple, we don't need more nuclear weapons or more nuclear armed countries, as we can destroy this planet several times over. Nor do we need more dangerous nuclear waste or fear of catastrophic accidents. Thorium reactors don't lend themselves to nuclear weapons production, and reduces the waste dangers. And it doesn't have to be thorium, but we can as least build them safer and smarter.
Nuclear power can be great for humankind, if we harnessed it more safely, to include using it on our moon, Mars, and beyond. On Earth, thorium is a safer and possible alternative. We need to get over our fossil fuel suicidal addiction, sooner, rather than later. Renewables are great, but its going to take us more time to get where we need to be, so nuclear power can help get us there faster.
Even Thorium based reactors still need decades of development and billions of investments to even start commercialization and eventual scaling up. Without a guarantee of success.
