Maybe. By all means it deserves investment, deserves the attempt, but it doesn’t seem much more practical than fusion

Cost?

• renewables are the cheapest power generation
• nuclear is most expensive, not economical
• thorium isn’t even developed for regular use

Time?

• renewables can be built asap, and brought into use incrementally
• nuclear takes decades to build, no one can afford that
• thorium isn’t even commercially offered
