Is the King's Indian Defence refuted by stockfish?

yeah thats true until you get deeper into theory for example move 20 and their are no games

exatly its better to focuse on openings that dont make suffer such as the grunfeld nimzo or slav those are way more practical

qeens gambit acepted is also good but not the qeens gambit declined

we can argue that the most challenging option is the othrodox variation and the queenside vs kingside pawn storm bayonett attack variation thing

whites attack is faster but that does not mean its an instant loss for black, he can typically still hold onto and endgame if he doesn't go wrong, alltthough white is still better

out of all my QGA games on lichess ive gotten alot of what you just showed, the best way i came up with is f3 with a follow up of Ne2 and Be3

ive always felt like 3.e4 was too risky due to e5 and the counter play black gets

Your talking about 5 min chess not classical also in time list under 10 openings don't matter

I agree but black is still always miserable in the l

Kings indian due to the lack of space Jeremy silman talks about the importance of space in his book reases your chess I think you should go ahead and read it or buy it

Not really if you play the right variations such as the samisch fianchetto variation or the fianchetto variations you'll be fone

Yes but you want to get a decent game not a game where your constantly passive and suffering from lack of space read Jeremy silmans reases your chess he covers more on this

Not really e4 might be winning

chess openings have a way of finding a balance. Since right now only a handful of super GM's play KID as mostly a must win side weapon with black, over time, the elites will begin slowly forgetting KID prep as too few players bother to play it to be worth, memorizing multiple sidelines 25+ moves deep. and then a new generation will begin experimenting with it and get a few great wins which in turn ups the prep further.
but it seems the days the KID is a world champion staple or even a super GM regular are long gone.
they are also plenty of openings waiting for a nice revival . which have little wrong with them, but havent been "Adopted" by a super GM quite yet on a semi-regular basis. Its a pity chess is such a voguish hobby sometimes, because at the "mere" 2600 level, you can find GM's playing almost everything that isnt busted.
Another relevant point is that at the high level, you either go from breadth or depth. If you do decide to play an opening thats on the slighly dubious end (and by this i mean, agaisnt really prepared strong opposition you will suffer even if not quite busted, this is usually more common with the black pieces as white openings where you are clearly worse are rarer) you have to find ways to discourage heavy prep agaisnt you. 
one way is to play lots of sidelines within one opening. This way even if your opponent wants to book some critical line agaisnt you, he has to roll the dice since you may not play what he studies or he really has to double down and learn all your sidelines. Even, then you would include 1 or two mainlines which dont have as worrisome critical lines so if you really suspect prep work, you likely wont be too bamboozled. 
e.g ,imagine playing someone that knows, 6 sicilian systems really really well. You will reconsider learning 25 moves of 1 line, if they you only have 16% chance of encountering that one line! Of course this is not only quite difficult its often not possible. You are up to the mercy of the opening to allow enough sound sidelines to pull this of. Secondary openings especially, dont have that many objectively decent sidelines, so its not always possible. 
more common, is simply to play lots of openings. imagine playing someone that has 7 viable ways to start with white, and a handful of sidelines in some of them. If you knew they played 1.b4 would you learn 20 moves of possible theory to get a tiny edge when they can play almost anything else? nope. Maybe in match play, world championship style events etc but not in your average tournament. Heck not even in a norm tournament most of the time).
