The UN predicts the world population will reach eight billion this November. That's eight thousand million munching their way through the planet's resources.

Motor mouth Harari, Klaus Schwab's advisor, suggests the "useless people" among them should be given recreational drugs and computer games to play to keep them occupied.

Presumably the useless will comprise of those too old or too ill to work along with those unable to because they can't compete with the new technology that rendered them unemployed and thereby useless.

I'm sure villainous, extremely powerful psycopaths could develop a plan to eliminate the useless rather than have them hang around with their feet up in receipt of Universal Basic Income happily puffing Morrocan Woodbines while navigating Grand Theft Auto until they conk out naturally.

The one I'd adopt would be to con as many of them as possible to volunteer to have a substance injected that will wreck their immune system to ensure their lives become severely foreshortened.

Does anyone have a better idea?
