You have to laugh at the over-claiming made by corporates.

 > Commonwealth Bank’s SAP-based core modernisation last year has 
unlocked about 90 percent of all its customer, account and transactional 
data, which it now hopes to harness for deep personalisation and 
behavioural banking.

The consolidation of silo'd data in banks was trumpeted in the late 
1970s, with CBC being the first to make the claims, and the others 
following over the next 5-10 years.

And you have to laugh about the marketing term "deep personalisation". 
Leaving aside 'private banking' for the wealthy, there's no personalised 
service on the bank's side, and no sense of the customer as a person.

In the era of 'digitalisation', they rely entirely on the 'digital 
persona'.  But 'deeply manipulative management of customer behaviour 
through a rich digital persona, abusing the original purpose of the data 
passing through the banks' systems' doesn't have a good ring to it.

In case evidence is sought for 'manipulative', here it is:
 >  " [fast processing of lots of data] ... allows us to do things like 
customer-based pricing, which requires millions and millions of 
recalculations every day to determine what is the best price for a given 
customer segment.”

With 'deep persona-isation', it's a customer 'segment' of 1:

Here's another wow! factor, in this case dating to the late 1990s:
 > “Previously, someone would make a payment and then they'd have to 
refresh the screen to see their balance update. Now that happens 
straight away.


And here's the seer's vision:
 > “We’re imagining what the next decade of agentic banking might mean, 
and experimenting with Bedrock and AgentCore around what capabilities 
that will give us to deliver more hyper-personalised behavioural banking 
[and] intelligent experiences to our customers,” Davies said.

I can't wait (literally) for "hyper-persona-ised behavioural banking 
[and] intelligent experiences".
