Theres a problem in the curriculum if EVERYTHING you learn is obsolete in engineering. Sure there are new tools available for M&S, CFD, FEA, etc. but all the underlying theories are the same. More power to you though to go back and "re-educate" yourself. I graduated HS in 01 and am still in school. 1 BS and 1 MS both in engineering...and that was enough engineering school for me. So now the AF is paying for a masters in R&D mgmt.
