A comment on ATMs didn't kill bank Teller jobs, but the iPhone did. Parent comment
That's not quite my read - the original says per branch there was a 1/3 reduction, but your comment appears to say 1/3 total redundancy.
There was, according to the original, a 40% increase in number of branches, meaning a net increase in tellers (my math might be off though)
edit:
100 branches → 140 branches = +40%
100 tellers/branch → 67 tellers/branch = -33%
140 × 67 = 9,380
100 × 100 = 10,000
net difference -620 or just over 6%
