The author has a good point, although he miscommunicates it: The common use-cases, such as servers, business logic, glue code, etc., don't usually require hyper-optimized performance. It only needs to be reasonable and predictable.

They need a language that is easy to work with, and share with others, and there are few that really do that.

But of course, there are. Go, Python, Julia and others I'm sure, all prioritize comfort over performance. Although, as compilers improve, they might one day actually become faster -- since the user writes more abstractly, there is a wider search space for optimizations.
