I'll believe whoever first powers a light bulb from fusion.

I can completely imagine that it goes through stages like

Half a century of painful research at universities -> decades to build multiple prototypes -> years to build a POC -> decades to industrialize the POC -> years to connect the POC to the grid -> ???? -> light bulb moment -> ???? -> profit

I'm not sure we much further than the beginning of step 2. Indeed, (sorry to say that), I'd trust an MIT startup to do that more than a YC startup. But real life will serve as evidence.
