I think this an interesting analogy. Taking it further - what's great about the Home Depot level skills is that they are often sufficient for me to be able to do routine basic maintenance. This is in-part because many things have become simpler and designed to be easily/cheaply replaced. I think the same could be said for software. That's generally a good thing and was an intentional movement in the industry

That said, I probably don't want to be building a house from scratch with my level of skills and should hire someone with specialized knowledge. Likewise it's also an important skill to know when you will be in over your head and when you need to hire someone to get a job done correctly
