DevOps is not about tools, DevOps "teams," or "engineers".
It's about aligning different people around shared goals rather than working in silos, each with their own goals and ambitions.
Tools help, no doubt. But that's not the point.
DevOps is about the culture you set.

If you know me, you know I've always been in favor of using the best tool for the job.
But that doesn't mean you should be adding tech to your stack *all the time*.
The best tool for the job requires context.
Adding new tech to your stack requires you to think carefully if it's really worth it.
