This is one of my absolute favorite quotes, and I've used it as a guiding star in figuring out what I want to do with my life, but it's also reductive in a critical way: time and energy are limited, and not everyone wants to generalize.
An example I've been running into myself lately has been trying to get a portrait photography workflow running with only FOSS tech. I've been fighting with darktable and libgphoto for months (and even tried submitting patches!) and tethered shooting still doesn't work right. I could continue sinking time and energy into this, but at the end of the day I just want to shoot tethered to a laptop, a basic function of modern photo editing systems.
I had more time when I was a student for learning how new systems work, but between full time work, the admin of being an adult, maintaining various relationships--I don't have the resources I once did, and I'm content to consider solving them someone else's problem.
The reason I go to my vet is so they can "troubleshoot" my pet. I don't have the expertise to do so myself; why would I expect the reverse to be any more true?
