Poster children for tech with no realistic commercial prospects. Projects in these fields have been pipe dreams for decades. Where are any commercial products in the areas of fusion reactors? Quantum computers? Asteroid mining operations?
If private investors want to fund this stuff, fine. As long as they don't come seeking bailouts later.
Not only that, but fusion itself is absolutely not what a tech venture capitalist wants to fund. The research horizon for fusion power is in the multiple decades. You're never going to find an investor that says "Yeah, I'll give you enough money to build a fusion reactor and do research for 20+ years in the hopes that you get something workable"
Fusion is literally still in the pure science stage that OP was telling governments to stick too.
General Fusion's approach seems pretty realistically commercializable. They're struggling to get any funding though, probably a symptom of being in Canada.
