Capable literally means having the ability to do something. Doesn’t actually mean you must do it. There are capable hackers who don’t feel compelled to take systems down.

There are plenty of trust fund babies who are intelligent and can output economic value. Doesn’t mean they do.

In Google’s case, the individuals can be capable but the org may not be. The sum is worst than the parts.

"capability is measured on output"

No, it isn't. That's effectiveness or impact. As an example, I'm capable of running 10 miles per day but can't be bothered.
