This ia a reply to [tor-relays] OT: How much Internet traffic overall is from Tor? from the mailing list.
I asked 2 AIs. Neither could answer. Both offered suggested ways to try to figure it out like relay stats. Both said it was too complicated, and lots of blah, blah, blah. One made an estimate that is would be less than 1%. This makes sense especially since we know that more than 50% of global internet traffic is non-human and by my speculation it is rising.
