That really depends on what you want to do - I bet there are still people making very decent living after learning how to make WordPress themes in 2005. Sure, you need to keep up to date and constantly learn, but you don't necessarily need to know details about how Apache works if you're just making a portfolio page. I don't want to discourage anyone from learning hard topics - it can be very rewarding and useful. I just object to the sentiment that learning how to use a tool has no value if you don't have an intimate understanding of it. It still gives you the power to solve new problems.
