The choice may have been different if we were to start the project now. But I believe that interfaces are what matters. Also, we kind of didn't have a choice on the frontend. If you would like to see, our migration layer and database schema design is written in Elixir and Ecto. As for JS, there are definitely shortcomings but performance-wise, Node is good enough on the server side for the time being.
Do you have any specific questions?
Do you realize how hilariously unbelievable it is that 11k BTC has been donated for new forum software and nothing has changed?
Do you ever feel like you scammed bitcointalk users that donated?
Javascript is slow... why the fuck would you be developing a 100 million dollar forum in javascript? "Good enough," seriously???. With all the bitcoin that was donated this is just insane... 2018 and no new software. Not even an alpha example to go look at.
