Because the headline goes along with all the people that thoughtlessly think ai is pointless, but the blog post itself is an incoherent mess that actually sometimes talks about how ai is useful and rapidly improving. It is a rambling mess. People who read it realise this. People who just read the headline assume it will say what they think. The chances that you made it through that whole thing are slim to none, but sure, maybe you read it, whatever. Congratulations, I'm sure it really improved your understanding.
