Having an idea is rather different from entertaining it, at least as I (and perhaps Luke as well) understand the connotations. I can certainly conceive of all manner of monstrous plans, but I do not share them because after assessing their morality, I decline to pursue them further. I do not look into how to implement them, because I do not want to implement them.
I suspect that Luke had a similar thought, acknowledging that while he may be able to think about a baby-powered reactor, for example, he does not want to draw up the plans for it, either for actual use or for the purpose of discussion here.
Yes.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
