Does GA look much different now than it did in 2004?
I would say it does quite substantially actually, I started flying in the early 2000s and this is what is different to me now
*Cirrus wasn't really around
*no Foreflight
*no iPad
*paper sectionals were a critical part of your flight bag, as well as an AFD, FAR AIM, etc.
*E6B
*BRS wasn't really a thing
*Fancy glass was reserved for the uber wealthy and airliners
*Adam Aircraft was the "up and coming" company
*you (or at least I could) rent Piper for $90/hr and the instructor was $20/hr. I am not looking at roughly $130 for the same slow beater and double that minimum for instruction
*CFRP and composite designs were reserved for very high performance applications, sailplanes, and boats
*there were no drones... if you wanted to fly a plane with a remote you spent thousands of dollars to tinker with a delicate machine that you would likely crash on your first flight out
*clubs didn't seem as eager to take your money, IE, you paid the instructor off the HOBBS time unless explicit ground instruction was involved. Many places now charge you "handshake to handshake" which tacks on an extra half hour minimum...
*a personal "jet" was still a dream, not a potential reality
*TBM 700 and the PC12 were still relatively "new" ish
I could think of more but that's what I came up in under a 1 minute. But I do grant you that ultimately we're still mostly flying the same old Skyhawks, Skylanes, and Archers as before
