From my understanding, the word "bot" is supposed to mean something that is working as autonomously as believably possible.
Within the past few years, I have read a lot of comments in social media and forums where people respond with accusations of people being a "Russian bot" or "Chinese bot". I can understand what they mean if they use "shill", but using the word "bot" means to me that the original poster is an autonomous web scraper or automatic program to vigorously defend or attack something. But the thing is, even if there is a nation-state-coordinated agenda to subvert online opinion, these things are still being conducted by real people, which I am fairly certain are still just regular humans. You can argue that programs like GPT-3 are generating the posts, but I think it's obvious by the flow and logic/emotional response chain between accusers and accusees that it is between real people because GPT-3 simply cannot handle pulling in knowledge of theory-building in a coherent, substantive way (at least not yet)—GPT-3 can only give the facade of having complex, novel thoughts and responses as is typical of heated discussions, but usually it is quite vapid. GPT-3 also doesn't typically make typos, nonconformist "nicely formatted" writing of humans, or use new information too well.
My conclusion then is that real people are pushing their viewpoints still, not "bots", but I may be misunderstanding the way the term is used. Or, has "bot" changed in meaning/use? Is it just a word used to effortlessly shut down opposing viewpoints? I'm trying to seriously understand how people use this word now.
But, as everything is virtual, you have no direct way to proof whether some virtual actor is human or software. Only the quality of their actions can give you hints on it. So people go around accusing people left and right if their arguyments are to much following the protocol, and don't show signs of self-thinking by their understanding.
This on this other side has an additional meaning in form of human bots. A bot technically does not nead to be all virtual and digital, it could be also a meatbag with wetware following a guidebook, just acting out pre-definend routes. You see this usually in companies, call-centers and propaganda-jobs.
This is BTW a funny roundtrip, as the original meaning of robot was coinend for humans who do braindead labor, just following the rules, not thinking on their own. It just later moved to machines.
