This reminds me a little of the "nosql is faster than sql" argument a few years back, or "Firefox is faster than Chrome". Let's just add a "now" and we're fine. Most programs we have now are so complex that none of them is really optimized to the max. Therefore the question is basically who spends more of his ressources on optimization.

But some problems are very tough to solve in some languages. Like in Java, it's very hard to avoid allocating everything on the heap. In C++/Rust it's trivial so you can get that performance boost without crude hacks.
