In terms of why caring - consider why to care for efficient markets - basically a solid competitive market would mean lower prices and costs which benefits everyone. Just on idea that it is coming for 'the longest time' and nothing really happening - One thing to keep in mind, a lot of the backend systems for financial services are very archaic and while not very visible, FinTech is helping a lot to improve efficiencies, which again would lead to lower prices in long run. One example - The SWIFT system which is the backbone of international remittances is basically a very very complex system of passing messages around... and with all the manual handling it is like a FAX machine rather than email. It is really that bad. Changes are happening there which reduce the frictions of moving money and the lower costs helps trade flows, workers sending money home, eases travellers on holidays, lots of things.
