Not so much controversial as logical.
Physiologically the short form content causes our brains to react differently. Small bursts of dopamine have an effect that results in feeling engaged.
One of the things that concerns me is the long term impacts at a societal level. It seems that short form content drives shorter attention spans and unproductivity through the continued scrolling as we constantly sit at the slot machine looking for next little bit of brain candy.
Don't forget it is important to get outside.
Do hard things.
Spend time with people in the real world.
Life is calling. Answer the call.
