If performance was the true goal then we'd just naturally see slow adopters unperform and phase out of that company. If you make good tooling available and it is significantly impactful the results will be extremely obvious - and, just speaking from a point of view of psychology, if the person next to you is able to do their job in half the time because they experimented with new tooling _and sees some personal benefit from it_ then you'll be curious and experiment too!

It might be that these companies don't care about actual performance or it might be that these companies are too cheap/poorly run to reward/incentivize actual performance gains but either way... the fault is on leadership.
