Of course it's not a requirement. The same way a knife isn't required to spread butter - you can use a spoon. If you were to attempt to keep up with say, javascript the way you used to learn you'd be left in the dust.
And as tge other person says, how do you define social media? Forums?
Monitors or anything backlit are terrible to read from for any length of time. Paper or e-ink is superior. I don't see anything wrong with lowering the contrast of text on a screen to compensate for that fact.
But it doesn't win in compatibility, battery life, display quality, controllers, refresh rate or the fact you can lose access to the Quest if Facebook decide to ban your Facebook account.
