This will come off as condescending, but I mean it with the best intentions. I see that you are relatively new in HN. Comments like these are nonconstructive and generally frowned upon here.

I'm not saying that your criticism isn't valid (or otherwise), but its preferable to include some actual notations, quotes or reason behind such statements.

Overall comment: Such blanket statements are insulting, and usually erroneous. All programmers are capable to learn anything else as long as they are interested and willing.
