This post makes big broad statements but doesn't consider the nuance. I think they are somewhat correct, and the reality is most people do have a "website", it's a page on a social media site where they post stuff. The accessibility for everyone to have a publishing space is one of the most incredible advances in civilisation.

However, the identity of the page, publishing under your own name is the thing that this post doesn't really cover. They mention not linking to their own old site as it has stuff that they did when they were a child. They really should have expanded on that.

Archive.org is both an incredible resource but also a risk to people publishing things that they later regret. We have a right to change our mind, grow up and become a different person. Under GDPR there is the "right to be forgotten", we are early in the societal development of such rights in relation to the internet, and they can be abused by people removing thing the public should have a right to know. However I believe this is an important right, and because of it I believe the right to publish online under a pseudonym is important.

So yes, almost everyone should have an online presence, and most do. But we should also have a right for it to disappear in time.

I write online for myself now and the communities I contribute to, not for my children or their theoretical children. Certainly not some random slooth in future.
