I am lucky that the article is alien to me. I work somewhere we do devops. I write code and tests etc. but I would unlikely go a day without observing something in prod either by telemetry, dogfooding or getting paged. It is a really cool way to work understanding the whole system (within the team remit of course). And vaguely understanding neighbouring teams.

To the comments dev and ops are different. They are! I think the magic is massive platform team support too. I am not troubleshooting why splunk indexes aren't indexing for example.
