The parent could be stating that late twenties is the average age of startup founders, not that that they are in their late twenties themselves. I do agree with you that someone who claims to pick up new languages in a week should already have picked up a few languages. The grandparent says they only do the _majority_ of their programming in Java, so perhaps they have that covered. I'd love to know what the other languages they've chosen are, and their dissimilarity to Java. I don't know how to evaluate their claim that they're a really_good programmer, given that it's a throwaway account. But then, given the data of this article, I guess no one does.
