I thought the AI experiment was pretty helpful and interesting. The AI was able to correctly generate most of the HTML and CSS code correctly, especially the basic styling and table structure. I did put the code in the HTML validator and found that it made some mistakes such as missing the title element, and a warning to consider adding a "lang" attribute to the html start tag. This experiment showed that AI can be useful for generating code quickly, but it is still important to review the results.
