Well, if they choose Infosys as a company to implement CBDC then at least we are safe for the next 20+ years, because there's no way they complete the project before that time :)

Governments already observe most every financial transaction, either because they run the money transmission system (ACH/FedWire/etc), or because countries with VAT send every invoice to the tax office. It's not clear how a CBDC is actually different from the current system, but insofar as it isn't different, it's not less private.

The Indian cdbc is being developed in-house by the RBI afiak
