The challenge is that in most projects, the things that make things "better" also hide entire galaxies of technical debt. The MongoDB debacle is an example of that problem, as is the outcome of Docker (images full of vulnerabilities, difficulty in making even the most quotidian tools like strace, etc. run easily, converting a known and enforced-common production userland environment into a hodgepodge of 'whatever', etc.) and so on.

Supportability, risk-mitigation, debuggability, etc. are all thrown away in most of today's environments. An awful lot of tech companies are running mostly on hope.
