The PID loop may even have potential in the development of wealth-backed currencies: https://github.com/pjkundert/ownercredit https://github.com/pjkundert/ownercredit. Imagine a currency that supports the creation of 'K' units of currency upon the presentation of any form of wealth with a market-determined price, and then uses a PID loop to automatically adjusts 'K' to guarantee no inflation or deflation. Perhaps a path toward the removal of "Usury" as the foundation of the monetary system? Experimenting with these concepts required a robust Python PID loop implementation, which was (surprisingly) difficult to find. A useful Python PID implementation is available in ownercredit.pid (get it with: pip install ownercredit).
