I have used GPT-3 and it works for most of the time. But it fails some of the time too. And thats the problem for use cases like programming or generating config files. Because if you cant trust the output 100% you are pretty much reading the output every time.

So, the only time save is that GPT-3 makes you type less.

In any case I don't type much anyway now a days. Its mostly copy paste from stack overflow update parameters etc.

GPT-3 will be useful, maybe a year from now.
