[Dune] "Mentats are many times more capable than any pre-Buterlian Jihad computer" Does that mean the 1960's computers of Herbert's present? Are our IRL 2017 PCs better processors than any thinker of the Bene Tleilax?

In short, did Herbert envision how many-times-over programmable machines would become in a relatively short period up to the end of the 20th Century and beyond? How comparable is a 'off the shelf' Mentat from my desktop PC? Let's discuss and talk in through.

I think you're looking at it the wrong way, it's not all just about speed or processing power.

Mentats are "many times more capable than computers" not because they can crunch numbers so much faster than a processer, but because they're capable of things that computers just can't do. Call it intuition, the "gut feeling", inspiration, or even just a spark of humanity, but mentats are capable of making mental leaps that computers just can't do.

A mentat is more than just a really good organic computer, it is a *human* computer, and that humanity adds something that just can't be replicated by a machine.
