The problem with startups building hard tech is it takes a long time to fail. Failures that take decades doesn't work in the startup model. Image working on a fusion reactor. It might take 25 years to fail. The failure may not be that your idea doesn't work, but because some other kind of reactor comes along that is a better business (ie, cheaper). At this point, you are now a world class expert at a technology that…
Former fusion startup founder here. This is a very good point. My startup took 6 years to fail and much of our competition at the time is still at it 20 years later.
