I think more you’re just at the absolute margins of engineering to get to escape velocity. Those constraints haven’t changed, so until some major material or fuel advance happens things will continue to go wrong. Probably the mistake is to keep relying on rockets and propellants. Need to think more revolutionary. But hard for a startup to do that, usually needs gov backing.
