It should be good for at least 5 years from now, if not more.
Funny, there's even some regression in layer backed NSView rendering where the app I'm working on is faster (in some aspects) in a macOS 15 VM than on bare metal under macOS 26.

I've got a couple things that I use which aren't yet up-to-date, and are blocking my upgrade.
OP said it should last for " at least 5 years from now, if not more." which I doubt. Maybe for light webbrowsing.
i use arch btw
In 2017 I built my first desktop PC from the ground up and got it running Windows/Linux. I just removed Windows after the 11 upgrade required TPM, and I bought a brand new Framework laptop which I love.
This is to say that Apple used to represent a sort of freedom to escape what used to be Microsoft's walled garden. Now it's just another dead-end closed ecosystem that I'm happy to leave behind.
So you haven’t had a Mac since 2017, but you believe all of us using Macs are stuck in some walled garden?
These comments are so weird. Gatekeeper can be turned off easily if that’s what you want. Most of us leave it on because it’s not actually a problem in practice. The homebrew change doesn’t even impact non-cask formulas.
Personally I never felt Mac OS was that locked down, but it has been over a decade since I last used it.
The only time I felt it was trying to delete 'Chess' only it to be listed as a vital system application. I know this isn't true but I would love it if Chess turned out to be a load bearing application for the entire OS. Like folks at Apple don't know why but if you remove it, everything stops.At least MS managed to remove the load bearing Space cadet pinball. Replaced it with a One drive popup that handles all memory management in the kernel ;)
Back to the original point, by comparison on iOS I definetly did feel the chains. One could fear Mac OS will turn into that but they haven't conditioned people yet.
And it’s not like I don’t use a gazillion third party apps and commands.
It reminds me of the distant cousin who lives out the countryside and prides themselves on not living in the city because the news tells them it’s a dangerous hellhole where everyone is getting mugged or shot on every street corner. When you immerse yourself in clickbait journalism the other side, whatever that may be, starts to look much worse than reality.
