> "I haven't seen any obvious competitive advantages from choosing a non-mainstream language." Just look at the market cap of YC companies started over its first 10 years and group by initial back-end language choices. It wasn't dominated by companies using Java, .Net and PHP. On the contrary, those using Ruby account for over 50% of the valuation. Those using Python (a far less popular language then than now) accounted for another 17%. PHP, JS, Java and .Net combined were at under 5%. https://twitter.com/logicmason/status/1371255029412233218 https://twitter.com/logicmason/status/1371255029412233218
