Counterpoint: if programmers wrote programs the way structural engineers designed buildings, ecommerce apps would take half a decade to build and the software industry would have just gotten around to inventing Windows Vista and jQuery in the last year or so.
If you're saying e-commerce would simply be consistent and secure product catalogs with fewer promotional and tracking dark patterns, web scripting would rely on a and extensible and functional library for manipulating markup documents, and a stable OS kernel with few dark patterns and no cloud accounts, many of us would be sold in a heartbeat.
I don't think you're making the counterpoint you mean to be.
Hmmm but that software would also last a century so… your point? Moving fast and building unstable software isn’t really that great.
Maybe that's okay.
