Unfortunately technological progress is not always exponential. An human landed on the moon 56 years ago and people back then thought space travel would be a routine thing today so it'll be interesting to see how things go
It's certainly not routine, but I'd say the privatization of the space industry that's unfolded over the last few decades is significant progress.
When I get depressed and look out at the world, I'm actually amazed at what I'm living through—the internet, space travel, electric and autonomous cars, smartphones. It's really amazing.
SpaceEx has made a ton of progress in space travel, granted it's not an ideal situation with it being a mega corp, but it moved a hell of a lot faster than NASA could have.
Perhaps someday we'll have individualized space flight like we have ownership over our cars and private planes.
Don't know what you're getting at by saying the galaxy will be ruled by mega-corps. Seems pretty democratic so far, and most of the things achieved couldn't have been without organization.
