This will serve them well.
Ever since the GFC big tech has not produced anything which actually improved the quality of life of the avg. citizen.
And the last huge leap was Windows 95, the rate of innovation slowed down since then, we just barely managed to collect Google and Facebook along the way.
It was Windows 95 which should have shown big tech companies the way. If you stop innovating, then people begin to look at the marketcap of the company and the net worth of the founders as well as the pay of CEOs and sure enough hatred among the public opinion starts mounting pretty fast. People get accostumed to the quality of life provided by big tech in a very fast manner, if the rate of innovation slows down then people will turn on innovators because of the wealth inequality that they see between themselves and big tech companies' insiders.
Microsoft was fighting for its survival a mere 5 years after the release of Windows 95, not because of competitors, but because of the public hatred against them had mounted and that emboldened the DOJ to sue them. It wouldn't have happened if the next iteration would have been as transformative as the jump from Ms-Dos to Win95.
Big tech has to understand that as complex as they are as companies, they are not much different than a bike, you can only slow down so much before you tip over and disaster happens.
They have their 300B cash warchest, they have their AAA+ credit rating, they have interest rates at an historic minimum. They have no excuse for the technological stasis
