His direct quote contradicts your assertion:

"When we have rewritten from Go into Rust, we found that it takes the same size of team and same time to build it."

Important part here being: rewrite. I would expect a rewrite to take less time, not the same time, than writing from scratch. Yet a Rust rewrite took as long as Go from-scratch project.

So to me, this implies the opposite, that Rust takes longer to write.
