There’s lots of things on the horizon that might make some of what we now do obsolete or unnecessary and this was the question that Denis Walter of 3AW posed to me and his audience this afternoon.

We chatted about recent technological and cultural departures from our past lives like phone booths, telegrams and aerograms, encyclopedias and year books, phoning the talking clock and car registration stickers.

And then looked further into tomorrow to look at new inventions that may take over and become ordinary within 10 years and make some of what we today obsolete and old fashioned including driverless cars and 3D food and general printers.

Take a listen now and then add your thoughts to the list of things we no longer have, use or do and the future list of what we will have, use and want.
