They have a lot of fascinating and useful DNA having gotten started in the UK before the US. The UK's regulatory environment for digital banking is leagues ahead of America's, w/r/t data access, APIs, etc. If they can persist UK style data features through their American rollout, they'll have something no other American bank currently offers.
While my strong suspicion is that the UK's push for digitization / interoperability in the financial sector stems from Orwellian nanny-state ambitions that would be right at home in China's playbook, it would be fantastic if we could somehow manage to empower customers with access to their own information without similarly empowering data-thirsty governments to surveil and oppress.
The scary parts are probably going make headway regardless, so cheers to the silver lining in the interim.
