60 years of very little progress. Unfortunately our generation decided to go on Facebook instead of going to space.
it will come in due course. Most probably you can't do Alcubierre drive (or any other promising FTL) on a planet surface or near large gravitational bodies, and the energy source for it is also most probably not environmentally friendly, so you anyway need to be in space to do it. So we need to build up starting from what we have - for now we can explore Solar system, like colonize Mars, build large space stations, etc. with fission engines, and with fusion (or with nuclear Orion like) we can get a probe to Alpha Centauri at up to 0.1c. Unfortunately, if one excludes Musk, there has been no meaningful progress in the recent decades, and that is puzzling and very disconcerting - the drive to kind of collapse/implode our civilization into an extremely stable state of highly connected absolutely socially cohesive planetary scale ant-city seems to be winning over the civilization expansion drive which has almost died ( and i think that is one of the Great Filters, and it is very possible that we will also not make past it).
GP>to go on Facebook instead of going to space
if it can't be fought, may be it can be harnessed - lets hope that influencers instagramming from the dark side of the Moon will provide a sizeable cashflow and popular support for the space development.
