It's only a matter of time until PyTorch will also dominate industry. It's always like this. Think how Ubuntu took over the server market because amateurs were preferring it instead of Redhat/CentOS. And when they became professionals or were in a position to decide, they also put Ubuntu on the server because this is what they knew best.
I'm not sure that's a great example, given that AWS mostly runs on RHEL-based OSs and Debian is still preferred for Docker. Ubuntu did not "take over the server market".
Here's a report that suggests the exact opposite:
"Don't let the revenue numbers lead you to thinking Red Hat Enterprise Linux (RHEL) is more popular than Ubuntu. By The Cloud Market's Jan. 8, 2019 count of Amazon Web Services (AWS) instances, Ubuntu is used in 314,492 instances, more than any other operating system, while RHEL is used in 22,072 instances."

Disclosure: I work for Canonical, but as an engineer; I'm not in marketing or anything and that's not my job. But I do get the impression that Ubuntu is way ahead in general use in the cloud, and is also the generally used base for Docker images (I don't immediately see how to get that statistic out of Docker Hub). I didn't think this statement was controversial.
