There's also then no accountability for when it fails. Not that we have that now, necessarily, in software "engineering", but in other engineering disciplines, we do.

A licensed engineer can lose their license (a huge professional blow) and be potentially civilly and/or criminally held liable for designs they signed off on that fail or violate appropriate ethical standards of their governing body, e.g. IEEE for electrical engineers.
