And it's just going to get better over time. It's obvious now when something was written by a bot, but I doubt that's going to be true for much longer.
But, it should probably be labeled as such. Giving such text a human name as the author is indefensible.
Why is it indefensible in your opinion? I think it is only fair that if I have a job of writing some output based on some inputs, and I define a process to do that that can be automated, the end product is still my labor, and I can sign it.
Later, after general AI, I will argue the opposite, that human-written articles should be labeled as such so I don't waste my time on them. ;)
