Gafam marketing strategy is pure genius. They give a lot away "for free": Tensorflow, Kubernetes, Angularjs, Golang, you name it, all while maximizing both specialized and mass media coverage. Then they collect the benefits on GCP, AWS, Azure and the like.
Combine all that free stuff and the fear to miss out and that's just too appealing for management to think rationally. It doesn't matter if nobody ever made a dime playing Go, everybody wants to build the next Alphago. Nobody will remember that most recent disruptive progresses are limited to image/pattern recognition - talking instead of general AI, superintelligence and technological singularity.
Calm down guys: computers have super-human arithmetic processing capabilities since the 50s at least. It used to be called a calculator. If computers didn't have super-human capabilities, we wouldn't be using them at all. Period.
As for customer cloud, the canonical example of a success story is Office 365. Alas, it gets about 50% negative reviews on Amazon (considering all versions and supports). A commercial success, not a popular success.
The truth is: so far, the billions $ pouring every year into "digital technologies" have been benefiting technology providers much more than technology clients. Sooner or later, clients will figure it out.
Looking at the Gafam stocks, the Digital BS may actually have peaked this summer. As usual, SLB is jumping on the IT bandwagon just when the train is coming to a stop.
