It's not always intuitive! Another incredible one- the silicon industry absolutely bends over backwards to keep using silicon and UV, instead of GaAs, E-UV, and other exotic processes. As much as silicon & UV can be a colossal billion-dollar pain in the butt, it's still easier & cheaper than E-UV. Or automotive engines. We have all sorts of technology tacked on around the basic ICE gasoline engine to make them better- the combustion chamber is just a tiny piece of the machine, which is tended by countless devices managing temperature, airflow, fuel flow, air velocity, etc. Tremendously complex compared to electric motors- but in the end, they are still more popular than electric motors because of the fundamental problem of batteries.
