>Having a ton of features has been proven in many occasions to be counterproductive. Paradox of choice, higher learning curve, etc.
Ok, let's see you need to get the numerical value of several big integrals. You have two choices:
a. Pen and paper plus calculator.
b. Computer with sophisticated computer algebra system
Learning curve in (b) is way higher. Alternative (b) is also way more productive.
Helicopters have also a steeper learning curve than cars.
>At least optional typing and macros are not considered to be universal benefits for programming.
So perhaps you don't know the benefits. Lisp Metaprogramming benefits become obvious after taking the time to learn them.
Optional typing dramatically increases execution speed, something that is very relevant and important in 2018.
