Yes, if you exercise blind faith in the official numbers, then you know.

How would you know how many 'people' are connected to the Internet?

Did you scan their retinas using the camera on their laptop or their phone?

Are we talking about devices, IP addresses or people?

It's like telling me, there are 5 billion people using social media. Well how would they know? Did every user send them proof of identification when they registered?

The thing is you have no clue how many people are connected to the Internet and neither do I.
