There are probably many reasons, but I think there are two ones worth mentioning (aside from money, which everyone else has mentioned so I won’t bother).

First, pretty much everyone is online now. The real greybeards of the internet talk about Eternal September which is when the internet first began to reach a larger audience in the early 90s. IMO the same thing happened (on a much bigger scale) with the advent of smartphones. The difference in scale between mid 2000s and now is difficult to imagine. And I just don’t think you can have a cohesive culture across such a vast set of people.

The second (related) reason is that you are a lot older now than you were back then. Most of us who grew up in that period just don’t have the same interest in memes as we used to. I presume younger people do have their own memes but (i) they are less likely to pop up on the websites I browse, (ii) when they do, they don’t interest me, and (iii) because there is so much more content out there now, each individual meme is probably shorter lived.

Irish and French. Irish was mandatory, French technically wasn’t but most (all?) universities required (require?) a passing grade in at least one foreign language regardless of the course. Anecdotally in Ireland most schools offered French or German as a foreign language.

Granted this was all many years ago so the system may have changed since.

People are suggesting Jellyfin which is a great solution for media like music, movies, etc. If you want to have offline copies of large knowledge repositories, like Wikipedia etc, look into Kiwix.
