I see your point, but I also think you can get into trouble deciding whether a degree is "pointless" entirely on its current market value. Computer science may have seemed like a pointless degree at one point during the 60's.
There weren't many folks with CS degrees in the 60s. (Stanford's department, which is one of the oldest, started in 65 and didn't do undergrad until the 80s.)
you never know what will be useful.
