The bit on "DevOps" is pretty egregious. There's two key things at stake here.
1. "DevOps" is an absolutely critical part of automation. It's the reason why we can start tech companies with such small engineering staff compared to 20 years ago. It's as important as all the high-level languages we use. This stuff is the logistics of how software gets deployed. It's the same in business as it is in war. Coding chops is like tactical strategy, and being able to ambush a tank column. It matters, and you won't have an engineering org without it, but the whole chain of how stuff gets deployed and iterated is what keeps the ammo flowing and the fuel pumping.
2. Universities want to teach stuff that'll still be relevant in 50 years. Given their proclivities, that means stuff like algorithms.
On one hand, I think that universities and academics can be somewhat forgiven for their ignorance on this matter. In fact I think we ourselves don't know what's going to be needed in our field in ten, twenty, thirty years. If the folks in industry didn't predict infrastructure-as-code 20 years ago, then the universities couldn't have taught it.
But what I know now is that:
- After all these years, no one is getting rid of shell scripting.
- Old school (i.e. 2nd generation) config management still has its place in many companies. Ansible is great for provisioning an AMI, if you need one, but if you need static infrastructure, puppet and chef are actually better because they track state, which allows you to better manage config drift.
- k8s may be hot and all, but a lot of the underlying "ops" stuff still translates. You average resource usage over pods instead of hosts, for example.
- Put together, there is an "instinct" for ops that is not unlike the "instinct" people learn for math, algorithms, and code. They are completely separate and an engineering org needs both. I think that universities don't "get" ops because computer science is more like math, whereas ops is more like history.
- On one hand, being stuck in an older ops paradigm is pretty awful – if you missed the transition to infrastructure-as-code, then it may be really, really hard to get out of that rut. But the field itself can be pretty bad with being stuck – it took us forever to give up our own datacenter racks.
- But otherwise, the old knowledge about old tools didn't necessarily just go away, in fact it's oftentimes still quite relevant. Linux internals (e.g. iptables) are still useful.
- When I was at CMU, a lot of folks learned some of that ops instinct in the dorm room, and in the computer clusters. But the universities pretty much made it optional. Looking back, I think this was a mistake. Ops is pretty much entirely transmitted through osmosis, whereas we at least try to teach people to code in official uni classes.
