I suppose it's how you define useless.
Philosophy more or less serves the same purpose as religion, except instead of being tribute to a mystical unknowing force... it's a tribute to ones own ego.
Just like religion, philosophy likely prevents a lot of people acting like objectivist dicks.
Can philosophy tell us anything interesting about the world? No. But it's in our best interest for people to think so.
This can be shown by this guy's response being posted... and nowhere in it does he remotely approach a point.
His two defenses of philiosophy basically boil down to... "Philosphers agree on stuff and people come up with new theroies and things change!"
and "Philosphy used to be imprortant for science before we got science down, so you should respect that."
Arguements you could eaisly make for religion as well.
