My take: Intelligence is the rate at which you can acquire wisdom.

I’m a mathematician. My math brain shuts off when the units are in currency.

You guys, the truth is way more depressing. They are not even smart enough to be as evil as you’re giving them credit for.

I think what’s happening is that each individual company has a positive ROI on ads in the sense that they would lose more than a dollar in sales if they spent a dollar less on ads, but collectively the ROI is probably smaller than one: if all companies would cut their advertising budgets in half they would all be better off, as they would keep their sales roughly the same.

So adverting is less about sales volume (people don’t necessarily buy more things when they see more ads) but about market share (you get a bigger piece of the cake). Classic prisoner’s dilemma.

Even in a country with „free“ healthcare, if you are at fault for the accident, your car insurance will have to reimburse the other parties health insurance for their medical costs.

Exactly. Why would anyone still use Arduino when alternatives are both better and cheaper?

That’s just because you’re used to it. The pythonic ternary is structured like spoken language, which makes it easier to read, especially if you nest them.

Is there an objective argument for the conventional ternary, other than „That’s how we’ve always done it!“?
