"are software engineers Real Engineers or not" is a pointless distraction. software engineers who don't know how to deal with guilt love to self-flagellate with it and other than that there's no basis in reality for that discourse. do something useful instead
nobody asks if electrical engineers are Real Engineers or not even though there's no licensing requirement for the vast majority of EE work and plenty of people do it quite successfully without so much as tertiary education

@whitequark practically it's more of a mindset than an actual title.

But sometimes it's fun to tease software friends and certain types of people with "Ah, but I have an actual engineering title"
