Lisp is for Weak Programmers

I love Lisp, and my Symta, as they allows me to quickly try a lot of design ideas. That is because I have a weak brain, making harder for me to plan and try them mentally, without prototype.

But most programmers are just too smart and can prototype directly inside their brains, so when they start typing, they already know exactly what they want. Good programmers can compile code on fly inside their brains and produce assembly - it will be a lot of typing and debugging some segfaults, but they will be implementing final idea anyway.

Take Unis for example, it was conceived in a few moments, while author designed a video game, and since then Unix design is almost unchanged for decades.

Let me rephrase what the OP is saying

This is partially correct. Lisp allows you to quickly try out a lot of designs. You have a weak brain, this statement cannot be applied to all lisp programmers. In summary, lisp lets you focus on design issues instead of language semantics. Your post in insightful OP.

You cannot really judge other programmers here, that's because YOU have a weak brain.
