No he really didn't.
Chip and PIN is really difficult to defeat if the legacy magstripe channel
is disabled. Card present fraud is virtually non existent on chip and pin
and in particular large scale breaches like Target are not an issue.
If they were, it would be fixable.

There is a difference between going to sea in a boat that takes on some
water and going to sea in a boat with a giant hole in the bottom. Ross
greatly overstates his case.
