Dinosaurs can't bail out, thoughDid the dinosaurs of old see it coming? And even if they did, would it really have changed anything? All things die eventually... that's what evolution is all about.
You think Apple and AMD are in a different boat? Their time will come. It always comes.
Not saying Intel is in this stage (they're nowhere near), but a big tech corp always dies slowly. The founders bail first maybe, then the more savvy investors sell, then the more ambitious employees switch, leaving behind ones who are essentially retired but still receiving income. Funny enough the valuation stays afloat for a very long time in that state as they ride out their past investments, usually paying it all out in dividends since they're no longer growing. That's probably Cisco, HP, and IBM.
