Let me guess, you aren't very good at this whole logical argument thing which why you're just wrong here.
Again, merchantable skill is subjective and based on the free market, so no, I could learn a "merchantable" skill in 2 hours. Cleaning toilets comes to mind as one very such skill.
You're just wrong. It's possible to learn skills in 10 weeks of 8-10 hour days, and learn them well. It's possible to become a junior programmer in that time. It's possible to learn a ton of different skill in that time. You actually meant mastering these skills, and just refuse to admit it.
I think it was a logical and concise argument.
Perhaps a better statement is: "any semi technical skill takes way more than 10 weeks to become productive and not a risk".
Are you happy now?
I'm saying that you cannot learn any skill to a reasonably merchantable level in 10 weeks.
Regarding hyperbole, we haven't forgotten "Rails Is a Ghetto" yet...
