Humans began to rapidly accumulate technological knowledge 600k years ago

Just imagine where we'll be 600k from now.

Unrecognizable as a species.

Long gone, having been killed by AI research probably.

In the fuel tanks of future Cephalopoda.

I was surprised to learn that octopus fossils exist that predate dinosaurs. I dropped all hope for their eventual world domination. If they haven't done it by now...

The past 100 years of development are unfathomable already - even though some sci-fi from 100 years ago was accurate, so there was some imagination of what things could be like already. I like to believe I can vaguely predict what the next 100 years will bring, but that's based in a cynicism that the big scientific discoveries have been done already.

But 1000 or more years, unfathomable. It's the one reason where I wish time travel or suspended animation was real, just so I can see what the future might bring. Assuming it meanders on as it has for the past few thousand years, and there's no Great Filter event.

I don’t think our species will make it that long. We will have scienced our way to some sort of singularity or be extinct by several hundred thousand years.
