As a result, for the next 5 to 10 years we’ll be compiling ES6 and ES7 code down to ES5, not using several coding techniques that we’ll tell ourselves are for compatibility reasons. We’ll fool ourselves into thinking that we’re writing really good code when the browsers will really be having to deal with the compiled ES5 code instead.
All because we fear breaking the web. Watch that “fear” word - it retards far too many things.
