bose uses space age paper cone technology. they don't need high quality parts as long as all their parts were space-age at some point in history

Nothing is WRONG with paper cones, especially if they are treated. People don't like to hear things are made out of paper but the goal of a speaker cone is to have low deflection, reduce harmonics, lightweight(most of the time) but strong.
Paper does all of these things very well.
...for about the first year of ownership...then heat, humidity, and simple wear and tear break those little fibres down, treated or untreated. And then you have MUSH...
Too bad I expect my stuff to last a lot longer than that. That is WHY kevlar, aluminum, etc. have become preffered choices for mid/bass drivers, and silk is unparalleled for tweeters. Paper cones sound good in the store...but everyone knows what they sound like

I wouldn't say Kevlar, aluminum and etc. have overtaken paper yet. They each have their own set of problems. Aluminum has harmonics which are caused in the breakup nodes of the frequency response. Kevlar is heavy (comparatively) so it had a high equivalent volume = BIG BOX only.
If your speakers fall apart after a year they must have been cheap(or you're exaggerating). Vifa(one of the most well known speaker manufacturers(drivers themselves) still make most of their drivers out of treated paper, and so does Peerless(subsidiary).
Treated paper performs well, has a warm sound, is cheap, and shouldn't be susceptible to humidity if made correctly. It?s a game of tradeoff's each material has its advantage.
So no, I would not say other materials have taken over paper(although metal composites are definitely widespread). Also for unparalleled tweeters you might want to look into ribbon tweeters as they can be quite incredible when used correctly.
