What do you disagree with? You just joined me in calling them children.<p>If society shifts such that most 18 year olds act like children, them perhaps 18 is no longer the appropriate age to consider someone an adult.<p>I&#x27;m not arguing that this is a good or bad thing, but childhood has been lengthened before and it appears to be happening again. There&#x27;s nothing magic about 18, it&#x27;s a function of the culture and if the culture changes...<p>&gt;What does it even mean to be an adult?<p>Most definitions of adult say something like: an adult is someone who is independent, self sufficient, and responsible for their own actions.<p>Now obviously being an adult (in the social sense) is more of a spectrum than a binary distinction, and those attributes I listed are more goals than hard requirements.
