Is it time to reopen technology’s cold cases?
One of the staples of crime drama is the ‘cold-case squad’. This allows programme-makers to add period detail to the scenes set in the past, while the present-day scenes can show implausibly attractive forensic scientists hunting for clues in a creepy location such as a long-abandoned children’s home (an activity obviously best performed during the hours of darkness by two people who separate in mid-search for no apparent reason). I have often wondered whether it is worth establishing a cold-case squad for technology and science, to investigate those lines of inquiry that went cold 50 years ago but would now repay further investigation; or inventions that suffered from a miscarriage of justice.
