AIs became so dumb and are becoming dumber every day

I remember days that ChatGPT could do complex tasks without any instruction but now?

I tell it to write a f*cking XML command to install Office and I want to see the setup. What he did? He made it hidden.

I tell it to check installed Python packages, guess what? He gave me a command to remove all my packages and I mistakenly copy pasted it without double check.

I need to explain everything to it. What the hell is happening to AIs? First Perplexity, then Gemini and now ChatGPT.
