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

I had a look at the Gemini capsule in the Smithsonian a few years ago. I was shocked at how primitive the controls looked.

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.
