For me, it's mostly information I want. I don't really need a full app for that. I want to know:
1) How much money do I have? 2) Did a check I cashed clear yet? 3) Are there any unusual charges? How is my spending this month? 4) Anything I should look into?
For actions I'd want to take:
1) Deposit check 2) Transfer money from account to account 3) Make a payment / authenticate with new EFT payee
All of that could be done conversationally, with a flexible level of detail. The data could be shown on any number of shared interfaces (messaging app, dedicated companion app, etc).
It doesn't obviate the need for software, and there are a ton of software ideas that exist today that will still be useful, as well as ideas that have yet to be discovered that will be useful. But...I expect the LOB app to go extinct in the next couple of decades.
