I don't think it had a focus on low level programming. It merely used people missing the difference between the domains best suited for each as an example of missing the point. Often the low level example was used as the example of someone missing the point. But I don't think that was intentional.

Its arguments are perfectly correct, however it exposes the state of mind that has lead us to javascript "apps" eating gigabytes of ram because they instantiate Chrome 3 times.

Yep, there's a price to pay when you're afraid of low level programming. Sadly you make us all pay that price.

I took it as an observation on internet arguments and not about the programming concepts that were presented as examples.
