Questions are now being asked on the future relevance of many industries

The disruptive nature of the coronavirus and the resulting economic shutdowns, is forcing many to ask new questions of old industries that have never been questioned before.

What will the future of air travel look like? If, as some have suggested, a vaccine for the coronavirus is not found - what then happens to the airline industry?

This is really a question of trust and our trust in the airline industry to keep people safe ahead of carving out a financial margin.

It was always assumed that at the age of 65 you retire and head off to a retirement home, to play bingo and wait it out until the fateful day of your passing.

But those old assumption are now being questioned - and the very existence of the old-age home is being probed for validity.

Many people who have been forced to 'retire', lead healthier and more productive in their later years than ever before.

Questions are now being asked of the validity of the regulations and assumptions that we still hold about age as well as the industries that supposedly cater for these decrepit old people.

Is this the end of the sharing economy?

Companies like AirBNB and Uber hinged on the assumption that people want and need to work in cities, but the coronavirus and remote working experiments have nailed a giant dart of doubt in that assumption.

Getting into a confined vehicle with a stranger, who's health status is unknown, just doesn't have the same ring to it that it did a couple of months ago.
