I would agree with that. A lot of these big companies have been around for a while and rose to power as PCs became prevalent in the average household, or when internet access proliferated and became part of everyday life. The idea that small startups will usurp large companies in nature industries is folly. Examples like Uber aren't valid because fundamentally it's a different kind of company based on technology. A better comparison would be what are the chances that a small startup, competing in the same market as Uber, will take over that industry or change the landscape dramatically? For PCs what we have is what we see right now in terms of companies and choices.
