I don't think our hobby will "die", it will always endure in some form or fashion. We all adapt and grow with what is available, popular, affordable, fashionable, whatever. Perhaps a bit like the rat rod era, which very well may have been driven by some of the factors we are addressing now, again?
Maybe some of the same issues that drove enthusiasts in the 40-50's to build what they did...working with what was available and affordable (no billet

)
Now I like my fair share of shiny, but I can't afford the pretty paint now or maybe ever! We're running our burb the way it is because we can enjoy it right now, while we modify/work on it and learn what it takes to take it to another level. We will eventually paint it, but will probably do it ourselves after we (my boy

) learns how! It's a skill we (he) would like to be marginally competent at

.
I don't know whether we get more enjoyment out of learning and building things or finishing and running them...I really think probably the first, it would explain why they're never finished??
