Harvey building TaxAI is very interesting. They seem to be expanding to other services https://www.harvey.ai/blog/harvey-co-builds-custom-model-for-tax-with-pwc

The most likely driver of actual tax reform that I can see is not legislation.

It’s open source E2EE software you run locally that does everything for you with precision and maximum deductions based on prompts it gives you. 

Seems technically feasible but there would be heavy lobbying to make this illegal.

True, but if it ever gets through, it could revolutionize how we handle taxes. The efficiency and accuracy would be a game-changer for taxpayers.
