What do you mean by "none of that"? troupe mentioned a lot of things, including ways to educate yourself and ways to get a diploma. Those seem relevant to me in areas besides just software development.
Oh - I may have missed a part of the post but the impression I got was that the resources / actions listed didn’t include the kind of accredited degrees which look good on a resume and that employers often care about. Like the online courses and such - few employers (I think?) put a lot of weight in those, especially relative to a decent college or university.
