Tourism to Mars and back (this is the easiest interplanetary travel) means years confined in a space rocket just to circle around Mars and get back (it is not possible to land on Mars and get back). Not that appealing…
Don’t worry man, the LLM’s will invent FTL travel before 2030. Trust me.
I know the GP mentioned making humans interplanetary, but I mostly just interpreted this as “more spacefaring”. By tourism I really just meant something along the lines of orbiting hotels.
