Actually a lot of people into music get tapes. I know in the horror world, a lot of releases get VHS stuff as collectors items, so both are doing well.

, you can buy cassettes at Target right now... and players.
Disc drive as necessity? Nah. Most games are digital, most people consume music and content digitally. Get rid of the drive and you just forced them to accept it all as digital. I know PLENTY of people with no drives.
Basically my point is, you naysay things that are coming back, but the thing that honestly IS dying you defend. Fans and collectors love the vintage crap, even if they don't use it.
Okay... several things, here.
First off, while there may be some people who collect cassettes and VHS for novelty purposes, or for the obscure, format-exclusive release, to say cassettes and VHS are doing well is just silly or pandering to a very low metric of success. New albums, movies and shows are coming out either digitally, on vinyl or disc. Only one of those formats is supported by modern, general media devices. Neither my local Walmart or Target sell VHS or cassette, by the way. Both carry tons of CDs, DvDs and Blu Ray, though.
Second, did you not read the part where I said, "as far as I'm concerned?" I don't care if you don't use a disc drive. I do. PLENTY of people do. And it's not just for playing music or games, as I've said. If I get a CD, I get digital at the same time, as, with a disc drive, I can rip the songs to my computer while also having the disc in my physical library to use with any of my several other compatible devices.
Third, recent researches have shown that physical media in music is actually defeating digital downloads in popularity. Streaming is currently the primary, preferred medium for music. Physical albums are second, outselling digital ones.
Finally, as I've stated, I'm arguing for basic practicality. CDs are FAR more contemporary than cassettes and FAR more practical. Arguing otherwise is just plain stupid. Hell, LRG survives on the idea that physical media still has a home in modern technology, and it obviously does. But to say that the most practical forms of physical media are dying and junk like cassettes and VHS are "coming back" is laughable, at best.
People can like useless, "vintage" shit all they want. I prefer shit that's both cool and good for more than sitting in a box.
