Terrible Article, I am surprised to see the from The Economist. It seems like they just want to name drop the most popular tech companies of late.<p>Facebook has just as much chance of disappearing in 5 years as it does of being around in 100 year.<p>Google probably has a better chance than any of these companies of being around in 100 years, they are in the oldest industry of all time. Advertising. Plus they have shown they are willing to invest in new technologies to stay current, ala self driving cars.<p>Amazon has massive potential, but by no means are they guaranteed.<p>Apple, Google and Microsoft all have ridiculous piles of cash, provided they don't make any stupid big bets, all of these companies will easily be here for the next 100 years just on these cash piles alone.
