I honestly think that $10/month is more than worth it. I found that having copilot is cheaper than hiring a junior dev. I mostly use it for C++, python, and TypeScript and has been really satisfied with it.
Scope of work for the AI: import jQuery, turn the dummy code into an ajax GET call, pass the clicked data between two pages, turn a PHP form into a JS one, add form validation, setup a POST call, debugging the regex of the phone validation from their backend team.
My scope of work: steal code from Codepen to do some drag and drop file upload and mess with the CSS to have it fit the page.
I actually train JS bootcamps and I'm sure 80% of juniors cannot do this within 4 hours. Nor would the good ones be hireable within such a short timeframe.
But it did help me keep the contract within the time I'm charging for. It was a $125 contract, so it would have been worth the price if it did half the work.
