Software engineering would probably be more of, well, more of engineering, and less of hacking, like all the other —thriving— fields of engineering, implying higher quality and more accountability.
Do you have any evidence to support that? I don't see that any software companies now do anything like engineering. Whether it's open source or not, "Software Engineering" is still basically just hacking.
Mostly just hacking. There are areas where quality and accountability matters. Space and aviation for example.
I'd say Windows and what came of that taught the common user horde to accept junk, so now it is hard to sell quality at a higher price regardsless of free software.
