@jawarajabbi @jzillw @cstross This is exactly how the banking system is, even large banks, & the work of integrating or migrating those systems is frequently farmed out to consulting firms (ask me how I know). It’s all fragile, held together with tape, & breaks all the time.
I’ve been away from that world for a bit, but I think it’s very likely those people would be looking at LLMs as a godsend.
