> A bank doesn't need a full-time development team for example.
all of the areas I mentioned are subject to constant change, mostly from regulators
implementing the Payment Services Directive, Solvency II or MiFID II all require developers
the developers working on the app/website that you interact with are always going to be a small fraction of the developers that work for a bank
and if you think this isn't the case (in a very cut-throat industry), I would suggest you start a bank and put the rest of them out of business with your vastly reduced costs
Edit: I realize this can be read with a pile of snark that I didn’t intend. Apologies.
That’s ignoring things like online bill pay, mobile banking, and roll outs of new financial products that really are innovations from the last 10-15 years.
