That's a rather #pessimistic take, and completely at odds with my experience.
I #program primarily in Python these days - but it's my fourth or fifth #language, not my first. It's well suited to many things - not all - and is easy to use, so I guess you could call it my "favourite".
I've worked with #engineers of every stripe, age, background, education... and I don't think any of them was stuck on whatever their first language was. In fact, I'm sure of it.
