Meanwhile, the Stack Overflow Developer Survey showed a massive jump from 25% of respondents using Linux last year to 40% using it this year. Even if you assume some sampling bias, that's still a huge swing.
Then you have major manufacturers like Dell shipping laptops with Ubuntu, Proton and Wine getting better and better at running Windows games and apps, projects like WSL and the Steam Deck giving more people the opportunity to try Linux out, etc.
Even if there are still flaws and barriers to adoption, those barriers are diminishing and momentum is clearly building in Linux's favor. It will only get easier to run Linux going forward.
It probably won't overtake Windows or become a huge competitor (at least, not in the foreseeable future), but I think in the near future it will become more of a "mainstream niche" like OS X was in the 2000s. Most people won't run it, but they'll probably know someone who does and it will be at least conceivable that they could run it themselves.
Which is all well and good for Google, but that's just not the kind of time horizon that open source projects can work on.
Judging from what I see from my family and people I meet, many homes no longer have any kind of desktop or laptop computers, and rely exclusively on mobile devices of various types.
The era of the 'home computer' will probably turn out to be a "brief" window between the early 80s and this decade. Some people who need specific functionality might have a laptop. But even there, tablets or other restricted mobile-type devices are making inroads.
