"Hi ChatGPT, here's a schema for an old MySQL 5.5.x table. Can you give me a "Legacy" play-slick case class and table class that reflects that schema, using Scala Play 2.8.x and play-slick 5.x? Can you rewrite that schema to a MySQL 8.x table, using your recommendations of best practices and naming conventions? Can you suggest the new schema to me in the form of a play-slick evolution? Also can you give me a slick case class and table class that reflects the new schema?"

I've rewritten portions of a legacy side project in three days, what would have taken me weeks without GPT4. And beyond the simple time estimates, there are the tasks that I just simply would not have attempted otherwise.
