Is bank robbing slowly dying out?

Well, if that is your definition, then bank robbery ended with the invention of vault doors that had time-delayed locks.
That was quite some time ago.

Only the dumb robbers try to physically take the cash from the bank these days. The clever ones can siphon millions of dollars from a bank in New York from thousands of miles away in Russia in the blink of an eye. Times have changed and the art of bank robbery has changed with them.

When was that? And crucially, did any of the celebrated big-time bank robbers post-date that invention?

(Most recent big-time bank-robber I can remember was Willie Sutton.)
