Linux is still not user friendly enough. Products from two decades ago are more user friendly than modern "mainstream" disros.
Look at Matrix and other OSS that wants to be mainstream. It's got awful UI/UX. And it's never taken off.
Gimp is an ugly beast with a bad name. Nobody's using that unless they're a Linux nerd.
I do see lots of people building retro game collections. Analogue 3D was a huge hit. Massive demand. It's sold out instantly five times. Palmer Luckey has a company building a similar product, and that's also sold out.
The clothing stores sell cassette tapes and vinyl. iPod and Zune are venerated.
My wife is Gen Z and into mainstream culture. She's all about retro. Polaroid, Instax, 2000's era digital cameras. The low end consumer digital camera I bought for $100 or so in 2004 is now selling for more than that. These things are wildly popular.
They're even hunting down old disposable one-use film cameras to pop off the lenses.
In any case, my wife knows this stuff. She doesn't know what Linux is.
