I absolutely agree with you and many that have been posting about this in the last few weeks. I think it's just so sad and stupid that this is even a problem and it makes those that investigate plagiarism more difficult. Ultimately though, I think this is a fight totally worth fighting because in the bigger picture, it's really our own humanity at stake here. Look at all the bots that took over Twitter and FB. It's a downward spiral.
For the actual content creators with skill though, they are going to have to increasingly prove themselves to be capable, making it far harder for average people to compete, no matter what AIs they use.
This is the part that actually pisses me off. I haven't been here all that long, but in the time that I have, I've poured a lot of time and effort, love and soul into my account and my posts. I mostly use only my own photos as well unless I'm writing a post that requires a stock image which is rare. It's going to become more and more challenging and possibly very demoralising if accounts start making it to the top earners when it's not even real, authentic human-originated content. It also makes it more difficult to work out who you can trust in terms of new accounts because scammers are gonna scam and I'm sure they are going to jump at this opportunity 🙄
And soon all the jobs that people got meaning from, but complained about having to do :)
But at some point, the technology for a half decent web of trust will help in this too, if only to identify scammers in the system. It is required globally already.
