Dude interviewed some people that did both software and other forms of engineering. Vast majority said software engineering is real engineering.
These are a few things that stood out to me.
In software engineering the gap between tradecraft and engineering is a lot smaller than the other engineering fields like electricians and electrical engineers.
Software engineering can iterate faster because it's cheap. If civil engineers could iterate like software engineers they would. New modeling tools are allowing this.
A lot of physical engineering defects are being fixed with software. 737 Max was given as an example where the new engine configuration made the plane unstable and it was fixed in software.
A lot of things can be learned from the different fields. All the other engineering fields wish they had version control. Software engineering needs more very focused deep dive books like this the other engineering fields have. Ex: https://www.amazon.com/First-Snap-Fit-Handbook-3E-Attachments/dp/1569905959
I was going to ask if it seemed to have overlap with this article. Then I noticed the author of the article is the one that gave the talk, so I'm taking that as a yes.
