It's the combination of pre-1.0 and having rapid development speed that is being questioned here. And it's a good question, not nonsense.

If you keep up the development pace you're going to approach stability. Unless you're in a manic spiral of rewrites.

Something can be pre-1.0 as long as there are no stability guarantees.

There is no benchmark. As a species, we don't even know know what a good programming language is, let alone how to reliably develop one. This stuff takes time, and we're all learning it together.

I like to compare this to real world cathedral building. There are some cathedrals that are literally taking centuries to build! It's OK if the important, but difficult thing takes a long time to build.
