This is an absolute terrible post :/ I cannot believe he thinks that is a good argument at all. It basically boils down to:

Here is a new feature modern languages are starting to adopt.

You might thing that is a good thing. Lists various reasonable reasons it might be a good thing.

The question is: Whose job is it to manage that risk? Is it the language’s job? Or is it the programmer’s job?

And then moves on to the next thing in the same pattern. He lists loads of reasonable reasons you might want the feature gives no reasons you would not want it and but says everything in a way to lead you into thinking you are wrong to think you want these new features while his only true arguments are why you do want them...

It makes no sense.
