Amen.

30 years ago we all lived in a totally different world, so alien to what we have today it might well belong into alternate reality fiction.

The only way we can deal with the change is not to think about it daily, and when we do we shade our sight with nostalgia...

30 years from now the world will again be so radically different it indeed merits calling in the men-with-straitjackets to take one away if one publicly speculates on what it will be like.

BTW, why limit your possible lifetime to 30 years? it might conceivably never end...
