Which begs the question is Software Eng'g/Development a mature profession? We've certainly been trying to especially in the last decade, arguably incentivized by ZIRP and VC money but the last few years?
I'm not just talking about tools either. You mentioned redundancies and contingency plans. Layoffs have stripped workforces to barebones headcounts. How can you have redundancy when one sick man-day reduces your eng'g team by 50%?
No, it's not.
For every sense of the word pair "less mature," including, but not limited to, "less responsible for consequences of actions."
