> Personal blogs aren't going to disappear, there's right now more of them than ever!

I'm not at all convinced. The personal blog, as it existed in the 2000s/2010s, is essentially dead. There are certainly still some sites which operate on that model - most commonly, in my experience, ones operated by professional authors or artists - but those, too, are increasingly rare.

In fact, I think this is an aspect of a broader trend - having a personal web site is increasingly uncommon. The default nowadays is to post your creations or experiences on social media, and to create communities within hosted services like Reddit or Discord.
