Amateur Radio is just a hobby and does not need to be useful or to have a point. Like many hobby activities, it offers a way to learn lots of useful things.
I think your distinctions about music and "usefulness" are simply your own personal tastes. There is nothing superior about a Drake song to a Mozart concerto.
There is nothing superior about a satellite phone to an HF transceiver. Each has its own relative strengths which depend a lot on context. It has nothing to do with the present vs the past.
Amateur Radio is not a nostalgia hobby any more than cooking is. Just because you can buy pre-packaged food doesn't mean you wouldn't enjoy a less pre-packaged version now and then. I'd also argue that enjoying Jazz or Classical music can be done for its own sake, with no nostalgia at all, even though you might argue that Drake has learned all the lessons from previous composers and artists and is producing an overall superior product today than was available in decades past.
But sorry, I completely disagree with you. Ham radio is absolutely a nostalgia hobby. It really offers nothing in usefulness over internet-based communications, unless you're one of those wackos who thinks civilization is about to collapse any day now. Normally, I wouldn't care much about it, because your second paragraph is mostly correct: a hobby doesn't necessarily need to be useful or have a point, and can offer a way to learn lots of useful things. My problem is that, for me, a hobby does need to be useful and have a point usually, and I don't see it here. I like electronics and all, but if I spend a bunch of time building a radio, WTF am I going to do with it? Chit-chat with a bunch of old men thousands of miles away? Yippee. I can't think of anything more dull. But what really annoys me are 1) expressing this opinion and being told I'm wrong (I'm not: it's an opinion), and 2) the constant whining I hear from ham radio enthusiasts about how the hobby has lost so much popularity, which is the only reason I even offer my opinion. I never hear disco fans whining about how discotheques playing 70s disco are all gone, but the hams are constantly whining about it. And then when someone explains from their perspective why they don't find it a worthwhile hobby, they get all defensive about it, as your post clearly illustrates.
I'm not sure who you are talking to about this :) The hobby has actually gained tremendous popularity in recent years. There are more licensed radio amateurs now in the US than ever before.
FYI this is Drake: http://www.drakeofficial.com/
I mentioned him because of your assertion that only the most modern version of something is useful and non-nostalgic.
> being told I'm wrong
You made a variety of incorrect assertions. I am not trying to change your opinion, just help you avoid making embarrassing false statements. I also do not believe for a second that you are unfamiliar with Drake.
