True in general, yes, but writing is an elegant solution where the longer something is, the more likely you are to write it down because you are less likely to be able to remember it. The shorter something is, the less likely you are to write it down because it’s a pain to get out your scratchpad (or iPhone) for ten words or less.

Yes writing can only augment human intelligence.

AI might replace it.

I do think it's murkier then that.

Writing "replaced" some forms of intellectual effort.

And it's yet to be seen how AI will play out.
