I am an employer and that's exactly what I did. This is amusing, but I would never want a person like this to work for me. He's basically saying "I know nothing and proud of it... but I can learn! I can pick things up fast! Hire me! Why wouldn't anyone hire me dammit?"
No he isn't. He just deliberately, explicitly refused to tell. I'd say this is a weak evidence that he indeed doesn't know anything. However, he clearly demonstrated writing skills. This piece is engaging and to the point. The ideas exposed are clear. Both emotions and facts are effectively communicated. To me, that's mildly strong evidence that he does know something.
As for why no one would hire him, I think he knows: because no one hired him yet. After the first month of job-searching (during which he made some obvious mistakes or just didn't have luck), he has to disprove the premise that there is no actual reason for his not being hired yet. As time passes, this effect becomes stronger and stronger. Some comments here that blame him actually ignore this, and if most employers do the same, they actually trigger the effect they ignore.
Ask yourself: say you see 2 applicants, one who currently has a job, and one who hasn't for several months. Which one will you most probably want to hire? Add in a few cognitive biases (they're not easy to overcome), and your decision may be based on this fact alone.
The one who hasn't, obviously. (S)he's had several months to develop undirected skillsets on personal projects, is less likely to be burned out, and would be far more likely to happily accept a lower offer.
The only solution I see to this problem is lying on your employment record. But I must admit I'm uncomfortable giving this advice.
PS: Outside of a tiny startup few people really risk much with any given new hire.
A good candidate does that during any job interview. Two-way filtering helps all parties find better matches faster.
I don't think he 'expects to walk in to a job' because of this, heck from the sounds of it his attempts to get a job have been largely fruitless.
This is just his way of standing out from the crowd and getting himself noticed enough for an employer to ask him in for an interview.
I don't have a problem with the guy asserting that he can pick up new technologies quickly, as long as he expects he will only be offered entry-level positions. You do not write Python the way Shakespeare wrote prose after six months.
I do however have problem with him not providing anything to back up his assertion. But he probably figures in a tight job market he needs to find a way to stand out, and this is it.
