Good for you, their point still holds up. Languages like Python and Go are more readable than awk and bash. They are designed to be that way, and many many years of effort have been put into them for that specific purpose.

Whereas if you know awk and bash, then they can be incredibly useful in a pinch. It doesn’t knock how powerful they are. I think it is worth learning. But if something needs to be maintained then there is an argument for Python/Go/whatever.
