... and where do the tools come from?

Tools are either made by expensive humans, or forged by the Dark Lord Sauron in the fires of Mount Doom.

There's also the matter of who will run those tools. It's not like fuzzers output exploit.sh or something.

Automation and tooling are great, but they aren't replacements for human ingenuity.

Oh no doubt, but tools scale well. The tools allow us to partially but cheaply replicate the brains of the expensive smart people.
