explaining how stupid it is.
I recall a conversation from 1979 when I was told that "colorization" of old TV shows and movies was "stupid" and would never be practical or affordable.
I recall being boggled at the concept of a 3D printer (replicator?) till I saw one in use last January. And already they have become smaller and more affordable.
And just a few months ago a work colleague's decade-long troublesome ligament was "cured" with a tiny amount of serum distilled from a pint of her own blood, in a successful clinical trial, which is now being written up in medical journals.
We can only imagine what the 23rd century will bring.
