This screed reads like someone who doesn't do testing. Or who only does end-to-end tests.

With both decent testing and decent monitoring/logging/o11y at each layer, no one should ever have to debug the whole stack at once and can instead focus on the layer with the problem.

I wish we could put the old days of having a tightly-coupled stack of untested cruft behind us.

this response reads like someone who's never worked in any size organization

even with testing I've seen all sorts of organizations mess it up, the tests become a negative cause they're not even used properly and just optimizing for "coverage"
