Some of them are good. Some - not so much. Aside from my universe my rules:
The first colonies will be either mining or agriculture. The whole point of colonies is resources extraction. If we build installation inside the moon the odds of it working a billion years from now are not that low. Any space engine that is manufactured en masse will be simple to operate and safe for the observer - we have good example - the ICE.
A lot of the stupid stuff are actually problems that we will have to solve for cross galactic space flight to exist at all.
