I'm old enough to remember people lying that compact discs were practically indestructible.
I think the early rounds of those trying to get people to switch to the format were motivated by the fact that tapes were easily recordable by everyone.
Disk rot usually happens when air gets in contact with the reflective coating and oxidises it. With CD's, it's actually the top side you need to be worried about, as it's right there under a thin lacquer coating. Any ding to that can expose the layer or just literally chip off a chunk of data.
At least on DVD's it's sandwiched inside the disk, so usually the only reason is a manufacturing error, and not really something the user can cause.
And I have PDO pressings of Faith No More albums that are almost 40 years old and have just started to rot. Common occurrence with PDO pressings apparently; one manufacturing error is all it takes.

Tapes tear and require mechanical parts. But it wouldn't happen were there not commercial interest.
There was a time before mp3 - pepperidge farm remembers! But yeah, now? I still have a cowon mp3 player that I just can't find myself to throw in the trash...
The CD wasn't really suited to be played Mobile (though I did have a portable CD player). It should rather be compared to vinyl in that regard.
I think tapes are great because no portable audio player ever came close to the Walkman regarding its cultural impact. The fact that anyone could record tapes opened up a lot of creative options.
For properly mastered music to be enjoyed at home on a potentially expensive setup, the CD was very close to perfect.
Except cds had better audio quality, you could shuffle or skip, they didn't where out or get "eaten" by the player, there was no rewinding or having to flip the tapes over, you could install cd changers in your car so you wouldnt have to swap discs around, and there was still no preventing you from recording a cd onto a cassette if you wanted. My old boombox could bootleg that shit easy as could be.
No one in or out of the industry wanted to keep cassettes. By comparison, they were trash.
