I'm not in the younger generation, but I listen to most of youtube (apart from songs and comedy) at 2x speed, and wish it could be even faster most of the time (that's a feature of premium, but I'm not paying for that).

The problem is that people are producing longer videos because that earns them more advertising revenue. Many creators now speak so mind-numbingly slowly, that even at 2x speed it feels like it's about a normal presentation speed.

In almost all cases, even at 2x speed, it would be quicker to just read a transcript (if that was available). The problem is really that people are incentivised to make everything into at least a 10 minute youtube video, when a short blog post that could have taken only a minute to read would have been sufficient to convey all the same information, and probably more useful as you could easily refer back to specific sections if you wanted.
