What do you want to achieve with it? They were still (super) unreliable last time I checked. Unreliable as in "you might as well roll a dice". Oh and they all say they are world leading, best etc.
Just note that there is no need to use evaporative cooling and new sites do not use it. The last article here about water and facebooks new site was a complete nothing burger because of that.
I am not the one who made the initial claim, but if you want numbers: about 2 % of sunlight is a shorter wavelength than UV-B or about 70 W/m². If you want the same irradiance from a lamp, all you need to do is get closer, unless the lamp is really weak. 5 seconds is simply nothing.
Why does the list grow? How? Who does that? And of course there are more details than just energy/nutrition, water on that list, those are just the most obvious and basic things. You also need breathable air etc.

If you argue like that, then nothing is necessary and the word can be forgotten. But how about we do not define necessary as something that needs to happen to keep the universe going and instead something people have to do to survive? Then we have another word to distinguish how important something is. And of course that is also how everyone uses that word, so using it this way is also simply normal and anything else will result in misunderstandings.
Let's hope so. And let's hope the next guy is not going to be Putin².
