FWIW, Chat GPT currently fails miserably at Tax Law.
It's unable to prioritize and apply the varying authorities in play (codes, regs, cases, IRS blessings & denials) to the varying facts and circumstances. And this is before determining the accuracy and truthfulness of the facts. It will be interesting to see how things develop.
