Note I ignored the 10x part. I'd find it a bit lame if a language came out that's 1.1x better than Rust because we're now in the awkward position of having rewritten lots of stuff in the second best language. However, should a 10x language come out you'll just have to swallow all that bitterness and start over because 10x is 10x.

Obviously a 1.1x language will come out - we don't just jump directly to 10x - and that's fine, fantastic even, but a little bit annoying when you're a language enthusiast and you've personally spent lots of time advocating for the now next-best language.
