Not especially. The computer program does all the work. It's the one that hits ChatGPT for a list of trades, and then the computer program hits the brokerage's API to execute the trades. I made the decision to set the program up in the first place, and the trades are happening on an account that has my name on it, sure, but as I'm not nit-picking each individual trade that gets made and it runs autonomously without a human in the loop, it seems fair to claim that ChatGPT is making decisions on what to buy on my behalf, even though I do have veto authority over the program and ChatGPT, and can stop it at any time.

My point was on the quality and reliability of the decisions
