I think the failing is believing there can be a "One True Architecture" in the first place.

A bunch of best practices around data handling, security, and general application architecture for specific use cases is useful.

Do my great new idea now or lose out is really awful and I've witnessed that kind of belief do irreparable harm to companies.

There's some parallel here to draw between the "new tech hotness" that appears every few years and the dancing fever plagues.
