Andrej K makes an interesting point and Autism Capital's dismissive reply is wrong.

It is rational to be more afraid of man than of nature, because it is rational to be afraid of powerful optimizers.

This is also often why we are more suspicious of for-profit versions than non-profit versions of the same activity.

I think AC was just trying to broaden the view of inputs to beyond Twitter.

Twitter should not be the be all end all, but for most it is... (or becoming).

IMO they were just trying to add POV that there is more than twitter.

Their way of saying 'go touch grass'.
