I suspect that it will be impossible, soon. People will just train LLMs to "act human," and pass the various turing tests we throw at them.
I stay pretty busy[0], and have been accused of "gaming" my GH repos.
That's not the case. I'm retired, experienced, and working on software all day, every day. I just don't get paid for it.
I also don't especially care, whether or not anyone thinks I'm a bot. I eat my own dogfood. Most of my work is on modules that I use in my own projects.
