I can say from experience that this is true.
I feel that I used to achieve a far deeper level of thinking before the advent of the internet.
Habits need to change.
I always wondered why passersby to a film/TV series crew shooting a scene in the street are so oblivious to what is happening.
I mean... many scenes take place on busy city streets or at sites teeming with tourists.
Places which are practically impossible to close off even for a few hours in order to film a scene.
And yet no one stops to stare at the big (or smaller) stars.
No one is even a tiny bit curious as to how a scene is shot.
Could all these people be so self-disciplined or just indifferent?
Could all these people (sometimes hundreds of them) be extras?
No. The answer is green screen (and CGI).
As you can see from the following, very enlightening video which contains scenes from well-known TV series (I recognized Ugly Betty, Heroes, Grey's Anatomy, Monk, among them), street scenes are at best filmed on a closed off street, and at worst, completely inside a studio filled with green screens.
So much fakery.
The video is from 2009, so green screen and CGI technology must have advanced even further since then. However, it makes me happy that when I watch contemporary American TV series, I can at least still detect this artificial and confined feel in most of them.
Update:
I just found the 2012 video of the same visual effects company (Stargate Studios).
They are just getting better and better at this.
Here are three cases of people who become internet celebrities and whom, surprisingly, I haven't featured here previously.
Starting with this lady, who became an internet sensation after she described her harrowing escape from a fire.
1) Sweet Brown - Ain't Nobody Got Time For That!
This guy also became famous following an interview on a local news channel.
2) Antoine Dodson - They're Raping Everybody Out Here!
Antoine Dodson
capitalized on his success by selling t-shirts and merchandise
containing his quotes, as well as receiving royalties from the "Bed Intruder Song" sold through iTunes.
This is a video from April 7th 2013, showing the very skilled captain of the ferry "Adamantios Korais", under quite bad weather conditions, coming into the port of the Greek island of Sikinos, unloading-loading, and leaving within 7.5 minutes.
Everybody waiting to board (especially the lady with the bags and coat) must have got drenched. And imagine the rest of the trip with the ship going up and down. Gives me nausea just thinking about it.
A few days ago I rediscovered a song that was a big hit when I was young in the early 90s.
It's "Informer" by Snow and I doubt any of us back then had any idea what the song was about.
Personally, I just thought it went something like this:
"In forma, you know sadarma stormy, I go blum, Aliki bonboner" (Aliki is in capitals as it is the name Alice in Greek)
Along with the original song, through the power of the internet, I discovered Jim Carrey's parody of "Informer", titled "Imposter", which is still funny twenty years on.
