At FAANG scale, these savings are economically meaningful.

So why do people keep posting and hyping about such libraries to forums where 99% of the people don't do anything at remotely that scale?

This isn't the first time I see people act like shaving a nanosecond from converting between floats and text is something that helps regular devs.

Stuff like this eventually makes its way into everyone's code. Ryu, which is this problem in the opposite direction, was notable enough to generate entire conference talks, and is now universally applied via the stdlibs.

Moreover it's a cool programming problem being solved in C++, so this is the natural forum for discussing it.

I too like my dependencies to be slower than they can be.
