There has actually been a few glimmers of hope in the PC industry...
Small form factor (Think: NUC), Enthusiast builds are actually increasing in sales... Which is why companies like Corsair and Newegg are still increasing in profits.
PC reached "Good enough" levels of performance back in 2006, 10 years ago for the majority of people who just use facebook, email and simple games.
People are thus less inclined to waste a ton of money in replacing it if it still works fine.
Ironically, mobiles and tablets have also reached the point of "Good enough" performance, people are less inclined to replace their mobile devices every year now... And that is affecting sales overall, pretty much any decent ARM A7 chip with a couple of gigabytes of Ram suffices for most.
However... If the PC sinks, AMD, Intel and nVidia falters and the entire market collapses... Then the flow-on effect will be massive for all other technology sectors, PC is where innovation tends to start, good luck with the next gen consoles using ARM SoC's.
What will happen from now on is consolidation and diversification, especially among ARM chip makers.
