Not sure if you mean to software developers, or to those who are autistic, but I'm both.

What's the less insulting but similarly concise way to make the same substantive point?

It is, and autism is just the swap-in vulnerable minority of the day that is socially acceptable to be the butt of the joke.

If you don't understand what I mean, swap out "autistic" for "retarded" and the joke still functions, but a lot more people will be offended by it.

I still laughed though.

It's kind of funny and also kind of insulting. I'd laugh if a friend said it but said seriously by some rando on the Internet, nah, find a better way to put it.
