There is no AI generated code on this site. After reflecting on my own use of AI, I think that its important to keep your skills sharp and know how to do things yourself.
LLMs (such as those for copilot) are powerful tools but you need to use them carefully. The usefulness of output from one of these models depends on a lot of things - the correct specification of the input, the data the model has seen, the user's correct interpretation of the output, and more. Two of these things require responsibility on the part of the user, and part of cultivating that is by making an effort to do your own learning.
Also, not using AI to build your site can reduce your carbon footprint a bit, and save energy for more important applications.
