Physical Vs chemical changes.
It was typically taught that physical changes are differentiated from chemical changes because they could be “undone” or that they had “no chemical reaction.” Which was very confusing, because you can’t uncut paper, and dissolving stuff in water clearly results in different chemicals being produced, yet both were examples of physical changes (actually the latter is sometimes taught as a chemical change). Furthermore, most chemical changes are actually reversible.
It has since been recognised that this classification is BS, and most changes actually exist on a continuum.
We were already there 10 years ago with Google Glass. Despite its failure in the consumer market, it found significant success in enterprise settings in the exact scenarios you’ve listed.
Except, all of these are scenarios in blue collar work. Apple seems hell bent on making this succeed in white collar areas with its emphasis on meetings, which is extremely baffling.
