There is reel to reel tape (for audiophiles), but that's expensive.
CDs are superseded by streaming/ 24-bit digital audio, but vinyl isn't.
But there would still be some recordings you can only get on CD, or on vinyl.
I do know reel to reel tape is still being manufactured. I'm a hipster douche and have a reel to reel tape player...for reasons. I also have a decent three head cassette deck as well that I use for tape echo.
A lot of using tape and "analog" (though people often confused "hardware" to mean "analog" when [pun intended] they're not analogous) are doing so because they want to explore those old techniques (tape loops, sound on sound, musique concrete, and as "lo-fi" color) and I think as a reaction to digital/daw everything. Unfortunately for them the time to get in to tape was probably 10-15 years ago when everyone dumped their four tracks, etc. There are kids today who have probably owned very little physical media in their lifetimes.
That said there are musicians actually releasing works on cassette, however, I am pretty sure they're all sourcing and using new old stock cassettes. I could be wrong, but I do not believe anyone is currently producing compact cassette tapes.
It's the same for guys releasing games on 5-1/4" floppy disks - they're sourcing new old stock for their releases. It's actually easier in some regards to manufacture a cartridge game these days because most cartridges utilize a standard edge connector and the PCB can be made in any fab house.
I don't think anyone is manufacturing 5-1/4 or 3-1/2 floppy disks these days.
