I recently used AI to make a plugin using a programming language I've never used before.
When working on similar projects in the past, I get to the end with a new understanding of the language and its capabilities.
This time, I think it took about 10% longer, was no easier overall (although each step seemed easier to start), and I feel like I still have basically no understanding of the language or its features.
If I were to start over, I'd still have to start learning from the beginning. AI has saved me no time at all, and the plugin still has plenty of subtle bugs I need to remove by hand.
Just a regular heat pump, but bending metals instead of compressing gasses. Same principle though.
