Blast from the past ...
Recently I had a brief glimpse in the future and the clock is being turned back. Not weeks, not months, nor years, but to a previous millennia.
It would seem as if, the times are a changing; it is if 1997 did not happen?
Now the competition is to guess … what is coming back as a core subject (albeit in another name) from a time now unknown, unless you were teaching this subject in the 90’s.
