There's definitely an issue in the devops/SRE world around understanding the totality of their stack. But I would submit that this is endemic to tech in general, not just devops/SRE folks. The combination of siloing and incuriosity isn't an SRE problem, at least not exclusively. Selfishly, it also makes things harder for me, as somebody who is a generalist's generalist, because people legitimately do not know what to do with somebody who's built and shipped mobile apps, can drop into a new piece of backend software and rapidly get up to speed, will architect, implement, and manage your cloud environment, and has hard-won opinions about rack cabling techniques. But I do OK regardless.
