That's the whole problem: With this local framing, it completely makes sense. But it's exactly the same with fossil fuels: Here and now, they are obvious choice

That's the whole problem: With this local framing, it completely makes sense. But it's exactly the same with fossil fuels: Here and now, they are obvious choice with practically no downsides. But scale those "close to nothing" downsides times 7billion people, 100k seconds in a day, 365 days a week. And suddenly, the ammount of time and electricity alone wasted on something like, waitiing for windows explorer to start, adds to real world scales. ...But also, this implies that optimizing is inherently costly. Which is not always the case. Just the culutre of 'not caring' makes things go slower then they could, while still using the same high level languages etc.
