FWIW: I'm probably one of the most "IT Conservative" people on this site, I still believe in sysadmins, dislike systemd, hate electron etc;
But there is something to be said about developer productivity: if you can build a prototype in 10 days when it would have taken 10 weeks that can be a huge differentiator between companies; it means you can make 6x more prototypes in the same time window, or work through different iterations of the same idea.
That's hugely beneficial.
I think if you treat inefficient things this way (I consider Ruby/Python in the same way) then we all benefit, test your ideas then go for gold on a more efficient platform.
