Did you read all the way to the end of the article? I did.

At the very bottom of the piece, I found that the author had already expressed what I wanted to say quite well:

In my humble opinion, here’s the key takeaway: just write your own fucking constructors! You see all that nonsense? Almost completely avoidable if you had just written your own fucking constructors. Don’t let the compiler figure it out for you. You’re the one in control here.

The joke here isn't C++. The joke is people who expect C++ to be as warm, fuzzy, and forgiving as JavaScript.

The other joke is a reference to Ellison's story, in case it wooshed.
