A single horseshoe crab, naturally deceased.

It was a great thing for Australia after some short-term pain, exporters saw how exposed they were to a single market and started to put effort into diversifying.

I think this has the potential to be big over the next few years. Imagine machine learning going nuts over every return for the last 7 years night and day for peanuts. Auto contacting people to provide receipts, it could likely audit a million people at once and not blink.

I'll have to look into it, surely someone has done an opensource implementation on GitHub that runs locally and doesn't need a third party.
