So far I’ve found copilot is like a weather forecast.

The shorter the prediction the higher probability of it being correct.

The longer, and more complex the prediction the less likely it’s all correct. But, with a close review you can spot the errors and correct it.

I’ve found most useful to get ideas on the page fast.

It’s also absolutely insane to be writing a parser, and have it suggest unit tests and code where it clearly has developed an understanding of the language before the parser is complete.
