Perhaps. More than a famous guru I find most companies badly need a testing framework that can simulate 90% of possible scenarios hermetically and lack somebody who can build that.

Once you have that and somebody has taken you around the block 3 or 4 times pairing with TDD on your app it usually starts to make more sense.

On my team after I inculcated the TDD habit properly, BDD came naturally. I didnt even encourage them to have conversations with the PO while screensharing the tests. They dont even know that's called BDD.
