I think the biggest shift in the last 20 years is troubleshooting in Linux and windows.

20 years ago and I had to troubleshoot issues and Linux. It genuinely required a good bit of computer knowledge to get it done. Sometimes hours of work to figure out how to get a webcam to work Or how to fix grub?

Windows back then used to be so easy. And there was usually something that would do a quick fix.

However, now and I run across a windows issue. It’s a nightmare. I can put hours of work into trying to fix a driver issue or an issue with updates and get nowhere. Then go to reinstall the operating system and have to spend more hours just to get it installed.

Now in Linux, not only do I rarely have issues but also fixing those issues are pretty straightforward. And if I can’t fix it a reinstall takes minutes and I’m back up and running in no time.

Nowadays I just roll my Linux installation back to before the updates using the BTRFS integration with the package manager. It works great and I’m never at a point where I can’t use my computer because updates broke it. Heck, even if I work it myself it’s no biggie.
