We went from fotolog to Facebook to Instagram to tiktok in a decade or so. In a few years more it will be something 3d we can't completely envision, who knows in a few decades. In each iteration language changes faster, cause memes are language.
In 500 years this will be gibberish. Who knows if people will even know how to read?
We already seem to be going to hieroglyphics, except that it’s with emoji and has dialects depending on where and by whom its used. I’ve seen adults unable to understand the emoji lingo that teens used to communicate a lot of things, and this developed in the span of a decade (or lesser) with the widespread availability of emojis. I can only shudder to think of how complex and divergent things from now would seem even 50 years from now.
It might not be gibberish. But let's pretend one possible next step is computer assisted/accelerated cognition.
Which means your incredibly interesting autobiographical web page which will be about as deep and interesting as an emoji, and hold attention for roughly as long.
Another possible - currently more likely - next step is extinction because of climate change, so there's no guarantee that OP will even have great grandchildren.
