It is suspension of disbelief, that somehow, there was only one practical solution to defeat Thanos. And they do not involve Thor going after his head, or Thanos educating the population of the universe about family planning and contraception.
ThanosWasRight is just a meme. Thanos could have gone for the latter option but his faux concern about overpopulation is a cover for his egomania.
Yeah, that plan wouldn't work. There are plenty of people today on earth, where we have endless access to education and contraception, who go out of their way to have like 12+ kids. They know what they're doing and simply don't care.
Someone telling people "Hey, be real cool if you like, had fewer kids" just isn't going to accomplish anything.
Just because there are outliers, it does not mean the whole trend is represented by it. That is to say, the population growth is already slowing down and may even decline after it plateaus. Education and access to contraception works.
The overall human population growth is actually slowing down and expected to plateau by 2050. Who would have thought that the more educated the population is, the less likely they are going to have tons of babies.
It is now the opposite, actually. Governments now want people to have more babies! But seriously, in this economy? And the future of the earth is not even certain it will be habitable for our descendants! Why bring life into the world that will soon be dead!
The subtext there might be that Dr Strange felt so hopeless about the situation that he didn’t conceive to look into the possibility, out of an infinite number of them.
I think he saw the one possibility early on but because Tony sacrificed himself there, Strange was trying to find anything else. That he couldn't after so many tries would certainly drive a person crazy, and it's reasonable to consider that if you only found one and no others, the probability must be virtually zero.
Seriously, why didn’t they stick his arm through one of those portals and then close it? Wouldn’t that sever the arm and separate Thanos far from the gems?
