We are already being convinced by invisible bots that have no mouths to talk with and no keyboards to type with. Go to any website -> all the ads that are desperately trying to woo us or nothing but AI/machine learning. Go to Amazon -> the product placement and results customized to you -> AI/machine learning. Considering Google/Amazon are already making boat load of money selling stuff indirectly and directly through this, I would say no new danger is coming by the way of Zeus's thunderbolt (aka GPT-3 as per ClosedAI's attitude).

Unless you are a bot and managed to convince me to spend a couple of minutes typing this answer - in which case - well played bot, well played! :D
