I haven’t thought about it in a while but the premise of the article rings true. Desktops are overall disposable. Gpu generations are only really significant with new cpu generations. CPUs are the same with real performance needed a new chipset and motherboard. At that point you are replacing the whole system.
Is there a platform that challenges that trend?
Honestly most people just upgrade the GPU and ssd, after 10-15 years they buy a new desktop. Also one of the biggest reasons to get a desktop is that it is cheaper than laptops, last longer, and you can change any part that breaks. I had many laptops with one component basically making the entire device useless, if it was a desktop it could easily be fixed, for example soldered RAM.
This isn’t against desktops. It’s against idea that a desktop is significantly more future proof than another form factor.
