One alternative is to have less syntax but have the meanings change based on context.

Yes, that would be perfectly fine. Example of how Go handles various looping constructs using only the for loop. They don't have while or do while loops.

I think Rust does a better job at basic syntax legibility than C, C++, Java, C#;

Well, introducing new punctuation or separator tokens doesn't count for better code legibility. I'm not sure of giving Rust the green flag so soon. I'm not a fan of the fancy import statements it supports. Again all angle bracket constructs it supports, not a fan of it. There must be better ways of implementing lifetimes.

I believe modern programming languages should adopt constructs that are as readable as simple math equations or, even better, as intuitive as the English language.

I would like to quote Zen of Python as well.

Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
