This is AI slop.

The point is that you’d also like to have good things done to you.

It really depends on how much you have to do, to be considered as doing ‘good’. Do you consider returning a shopping trolley as a good act? It’s a simple, small act that you do have to go out of your way to accomplish, and it brings some utility to others, which you might unknowingly be a recipient of.

That’s not to say you’re expected to return every trolley in the carpark, or that all the evil corporations are actively trying to exploit this for free labour.

Society requires that people do good to exist, while continued Evils tend to slowly destroy their community.

This really depends on your tap water; in some places tap water is clean enough to work, but it seems yours is not. If you want something to just set and forget, you’ll probably need to do more localised research. E.g Hardness, turbidity, etc.

I know very little about electronics. If Impedance is analogous to resistance from AC to DC, how does that equate in terms of the common water-electricity analogy?
