Saying stuff like this is sure to please the hacker-news hipsters. But... is this honestly anyone's experiencing using new web technologies?
I tend to be on the bleeding edge of tech, and I very rarely regret learning a new technology. And I do not feel like I am wasting all of my time flitting from technology to technology.
I just think this is a smarmy attitude disguised as wisdom. People should like what they like. And as someone who has had to climb that hill before: Waiting around not expecting the world to change around you is a losing bet every time.
The fool doth think he is wise, but the wise man knows himself to be a fool.
