Contrary take: I believe we will see an expanded market for capable PCs that can be sanely put in a living space. By extension of the gaming PC niche to local AI. Both NVidia and AMD are developing product lines in that direction (DGX Spark, Ryzen AI Max). And Linux will be more prominent than ever, due to several independent reasons: MS dropping the ball hard on Windows, SteamOS making Linux attractive for gamers, 'digital sovereignty' as a trend, and Linux being the de facto standard for hosting AI (or anything really).
Great take, but if the market is expanding for capable PCs why are motherboard sales decreasing?
