I guess this is apparently an unpopular opinion and I'll probably be downvoted

You will be long dead before EDM will be.

Do you mean EDM as festival-oriented big room, progressive house and trap or EDM in its literal definition of electronic dance music as a whole? This is why I hate the term EDM. You could either be completely right or completely wrong.

Big room, progressive house and trap will inevitably lose a lot of their popularity within a decade when something new comes along. I'm really sorry to say but it's true that these three big genres will figuratively die long before you or I do of old age. There's no two ways about it. Dance music runs in cycles. It happened to trance, it happened to dubstep, it happened to techno, it happened to big beat, the list goes on and on. They were all #1 at one point or another and while they still exist they're largely shells of what they once were in terms of their share of the popularity then versus now.

Big room and trap only truly took off to undeniable main stage levels of fame around 2013 and the current style under the progressive house moniker only goes back to around 2010 or 2011 so this is all still new. It's inevitable that they all will either fall out of fame or evolve drastically to the point of being nearly unrecognizable.

Now, for EDM in the nuance of almost wholly synthesized music with strong electronic and dance influences in general, you're right in that it's not going away. Upbeat music has been continuously popular basically since the 1890s and the integration of the full extent of modern technology is just a natural progression into the current era and continuing on. But "EDM" in the marketing sense will die once something new comes along.
