I don't see the point of this tool, independent of the resulting code being derivative of GPL code or not. being able to produce valid code is not the bottleneck of any developer effort. no projects fail because code can't be typed quickly enough. the bottleneck is understanding how the code works, how to design things correctly, how to make changes in accordance with the existing design, how to troubleshoot existing…
It doesn’t calm to solve the bottleneck either. On the contrary, it clearly states that its mission is to solve the easy parts better so developers can focus better on the true challenging engineering problems as you mentioned.
That doesn't help anyone!!
I am usually pretty pro-Microsoft, but this tool is a security nightmare and a bad idea all around. It will cause many (most? all?) who use it far more work than it saves them, long-term.
