I remember that IBM was famously missing the trend in the late 80s/90s and couldn't understand why regular consumers would ever want to buy a PC. It's why they gave the PC clone market away, never seriously approached their OS/2 thing, and never really marketed directly to anybody except businesses.
Microsoft really pushed the idea that regular people needed a home PC which laid the foundation for so many people already having the hardware in place to jump on the internet as soon as it became accessible.
For a brief moment it looked like a toss up between Microsoft IIS webservers serving up .asp files (or coldfusion .cf - RIP) vs Apache pushing CGI but in the end the Linux solution was more baked and flexible when it was time to launch and scale an internet startup in that era.
Somebody else would have done what Microsoft did for sure, had they not been there, and I suppose we could be paying AT&T for Unix licenses these days too. But yeah, ultimately both Gates and Torvalds were right in terms of operating systems and well timed.
"Ever" is a long time. Human progress seems to come and go based on need and economics. At the moment we seem pretty distracted by local problems and I don't think any of us will still be around by the time humans kill the Earth, so it doesn't seem all that pressing.
But someday the technical issues will be solved and a sustainable habitat will be able to coast through space for however long it takes to travel beyond Mars to somewhere else interesting. When it's possible, I think some people will do it, perhaps a lot of people.
It's a worthy goal. As a human I feel some motivation to ensure the continuation of our species so I would lean towards any efforts that involve sending some backup copies of our DNA to some off-site storage.
