To make a parallel with Microsoft in the early 00's and IBM before that:

> Although there is some truth to the fact that Linux is a huge threat to Microsoft, predictions of the Redmond company’s demise are, to say the least, premature. Microsoft has an incredible amount of cash money in the bank and is still incredibly profitable. It has a long way to fall. It could do everything wrong for a decade before it started to be in remote danger, and you never know… they could reinvent themselves as a shaved-ice company at the last minute. So don’t be so quick to write them off. In the early 90s everyone thought IBM was completely over: mainframes were history! Back then, Robert X. Cringely predicted that the era of the mainframe would end on January 1, 2000 when all the applications written in COBOL would seize up, and rather than fix those applications, for which, allegedly, the source code had long since been lost, everybody would rewrite those applications for client-server platforms.
Google has more money than Microsoft had back then and Google's product-market fit has been amazing since day 1. Any 1 individual (or even 100 individuals, 1000 individuals) could mess up royally and Google would still be around in 2050 :-)
