I'm not a huge SpaceX watcher, but I suspect it's harder to build electric cars than rockets. Yes, rockets are crazy expensive and time consuming but the fundamental principles are relatively understood. https://qz.com/1244768/why-are-electric-cars-so-much-harder-to-build-than-rockets/ https://qz.com/1244768/why-are-electric-cars-so-much-harder-... Tesla's continual hitting of projected targets is much more impressive to me. You're generally right though: the maturity, risk, and timelines of fusion are much greater than either of these. Better suited to long-term gov't/military spending. But the general principle applies. Everything is measurable and can be modeled with a predictive distribution. The more unknowns, the more variable the distribution is.
