You can also play with it to try and get closer to correct. I had problems with getting an Excel macro working and getting unattended-updates working on my pihole. GPT was wrong at first, but got me partly there and I could massage the question and Google and get closer to the right answer. Without it, I wouldn’t have been able to get any of it, especially with the macro.
Thankfully it is easy to not connect them. The newest TV I bought I connected it once via Ethernet during setup to get the latest software, then unplugged it. Has been working fine for a year with no issue.
