What will people in the future think of us?

Surprisingly, this isn't another political post about Brexit (though I do wonder what what historians will think of us in the future...).  Today a friend shared a video on FB about how almond link is made:

On watching this, my immediate thought was what would people in the future think of this?  

Suppose there was an Earth-changing event, people were struggling to survive, and there were limited resources.  Maybe the internet* didn't work, but there were pockets of servers around the globe where fragments of information can still be sourced?  Maybe there was a retaliation against knowledge (some days it sure feels like that!), and all libraries and books were burned?  Suppose that the human population had decreased to such an extent that much knowledge was no longer in the human psyche.  People were struggling to grow crops, the world was vegan because we couldn't afford to grow meat, and someone came across this video about how to milk almonds...

What would they think of us?
Would they know that it is not real? That it is meant to be humorous? Will they try to breed almonds?

Or will they know it won't work, and assume that we're stupid? Perhaps blame this stupidity on the reason why the human race is near extinction?

I admit, I may have read too many dystopian and post-apocalyptic novels and watched too many movies, but still.  I do wonder sometimes what the future will think of us...
