Even if you accept that, the cure may be worse than the disease. You'll lose programmers in under 2 years if they have to maintain a mishmash of learn-as-you-go style code with multiple quirky build and deploy systems, which seems to be a common result of the "write it in a new language" attitude.

When you're learning a new language you usually end up with unidiomatic code, and can't use the language tools effectively yet. The most "exciting" languages may not even have a stable tool set.
