It's not really comparable to a pen. Because a pen by itself doesn't copy someone else's code/written words. It's more like copying code from Github or if you wrote a script that did that automatically. You have to be actively cautious that the material that you are copying is not violating any copyrights. The problem is Copilot has enough sophistication to for example change variable names and make it very hard to do content matching. What I can guarantee it won't be able to do is to be able to generate novel code from scratch that does a particular function (source: I have a PhD in ML). This brute-force way of modeling computer programs (using a language model) is just not sophisticated enough to be able to reason and generate high level concepts at least today.
