So if we're at 7.5 billion now, that's 15 billion by 2082, 30 billion by 2147, and so on. 
 
By 2600, at that rate, we'll have 3.8 TRILLION people on the planet. 
			
		 
	 
 Well this is way short of Howking's figure. I half arsed crunched his numbers, but didn't bother to post the workings. It was hundreds of trillions. 
 
He's definitely talking out of his arse. He's just throwing shock numbers out there because he knows that lots of people have immense respect for him, know he's very clever, and thus listen to him. He probably gets a hand job off a honey government employee in return for saying things like this.
