From an AI safety perspective, I'm also worried it will accelerate the transition to self-learning code, ie. the model both generating and learning from source code, which is a crucial step on the way to general artificial intelligence that we are not ready for.
They also built a program that outputs open source code without tracking the license.
This isn't a human who read something and distilled a general concept. This is a program that spits out a chain of tokens. This is more akin to a human who copied some copywritten material verbatim.
