I worked for the largest online news site of Switzerland. We were nowhere near the scale where such tools would provide significant benefit over the "boring", "outdated" technology we we using. We also had a fraction of the operational cost than our much much smaller competitor within the same publisher that went full hipster on their tech.

Thing is, it for a lot of use cases it is a whole lot harder to get to large scales from a business and product perspective than it is for good engineers to adapt to it.
