I have heard that gem for about 2 decades now.

When the reality is more cpu/memory usually cleared things up. In the old times a good defrag did not hurt either.

People blame themselves when a lot of the time it is rubish software/hardware.

Then you have the other side of that coin. The yes clickers. If it asks a question just answer it however you need to do for whatever it is you wanted to work. Surprising number of dark patterns on that gem... Then they hand it to you and expect a miracle in 5 mins. Sorry this is the first time I have every seen something like this it may take me a few mins to figure out what is wrong before I can even begin to fix it.
