You study 6 years CS, then start your first job, how do they treat you? - like a beginner,... which has to learn,... "like everything".

"It's product-know-how that counts", but also "a good theoretical foundation" (for thinking logical, and believe me, it is better for everyone if you have that). So 6 years of studying + years of experience (for each product), the more the better.

Unf. you are mentally fittest between 20 and 30. Youngsters may make up with that, but I don't worry about my future.

It's not that 6 months is too little, it's that nothing is ever enough (and more is always better).

I guess some young startup guys may disagree and yes, there are Marc Zuckerbergs, which escape the law.

I don't want to hold you back from trying to escape this law.

"Unf. you are mentally fittest between 20 and 30. " -- not in my case. My best work and all my patents have been in my 40s (so far, still there).

You are underpinning my statement:

It's that experience (a lot of exposure in the area) is very important.

It doesn't invalidate that when you are young you are mentally fitter.
