i could argue both sides, but why bother. Some forums still seem active and have adapted decently, others haven’t.
Yeah, I mean, reddit still gets plenty of traffic, if you consider that a "forum".
The Anandtech forums are a great place, but it's kind of a dying hobby. For example, this is the first year I've been confident rolling out cloud VDI with DCC functionality professionally. Any device, anywhere you can get an Internet connection, and you get a lag-free Windows computer you can do real work on (with multiple screens, even). OnLive tried (and failed) a number of years ago, but I wouldn't be surprised to see PC gaming make a major shift to a cloud subscription model for hardware within the next five years. It "works now". And a lot of our forum is hardware-based, so without that, there's a lot less to discuss.
And even
with that, the game has changed in so many ways. You can reinstall Windows 10 from the internal reset feature or via USB stick in no time with no complicated installation procedure. Hardware has been "good enough" for years now, since cheap, large flat-screens & quad-cores & SSD's became available. Windows is actually stable. Macs are great. Heck, my wife is still running her Hackintosh from 2011 and the only upgrade we've done is to get a larger hard drive because we ran out of space, lol. A ton of people are using Chromebooks, which are zero-maintenance. Even more are using tablets or just using jumbo phones. And those smart phones replace literally everything...
