There's a difference between critiquing ideas and ad hominem attacks. "Think smarter" is so vague and nebulous it can refer to anything you want it to. This is the first time I've heard it refer to "focus", as that usually falls under the category of... "focus". And certainly it's the first time I've read advice to "think more thoughts" claim to mean "focus on one thing", and "think faster" claim to mean "spend more time on something".
