> The fact that they converged on a practical trade-off
Is it even desirable to mass produce at one specific point in the tradeoff curve? Wouldn't society, or at least engineers, appreciate being able to choose where in the curve you land?
Only if the choice is clear and reliable. Right now there seems to be a lot of difference between LED bulb longevity, but it's basically a dice roll if you get a lasting one or not.
