In so far as the software industry is much more lenient about that sort of thing, yes - mostly what they care about is Can You Do The Thing? without being so fussed about credentials. In broad terms for that field, you are not wrong, but only to an extent.
Structural engineers do not and cannot tolerate that. When buildings fall down people get killed in huge numbers, and during the investigations that follow, the first thing they say is "show me who was in charge of the calculations and show me what his record was". Engineers have gone to jail for oversights that have led to loss of life. The industry has therefore understandably and correctly been incredibly anal about who gets any kind of responsibility to design important structures, and about what kind of education and training they had.
Indeed, going back to software, you'll find the same thing happening when computers are deployed on life-critical systems. Bill Gates may have written Windows, but when contracting to air traffic control systems, Microsoft did not send their college dropouts.
Ultimately, Bill Gates, Steve Jobs, Mark Zuckerburg, and the like were people who very easily COULD have finished college but decided that opportunity was lucrative at the eleventh hour. It is highly misleading to hold them as an example to follow to someone who would drop out of college with no evidence that their capabilities had improved for the time they spent there. And don't get me wrong - that's not to say that their time in college didn't have a positive impact on their skillset, but my point is that some systems are too important to be managed by people who don't have evidence of their capabilities. Aircraft design is definitely one of those systems.
