Things that should be true...

• Squirrels should lay eggs
• The plural of platypus should be platypode
• Platypode shouldn't be endangered: then we would know what they tasted like
• And the same applies for platypus eggs
• A duck should be a common house hold pet - like the dog
• Different animal species should be able to cross breed and produce wild and wacky combinations. Like the platypus. Oh wait..
• Humans should be able to photosynthesize light and produce glucose as a food source
• Flying cars are way overdue.
• As is the hyperdrive
• And the human teleporter
• And human colonisation of the solar system
• And let's not forget strong AI
• From which point we can all stop working and entrust the menial labour to our robots.
• What could go wrong?
• Or right?

Ad infinitum.
