These same exact cells are still alive today, 50+ Years later.
Now I'm imagining a grey goo situation where the cells eventually overtake the entire planet
Some say the very same cells are being cultivated in certain corners of the internet.
I totally expected Gey to be pronounced like Gay.

I recommend reading through "The Immortal Life of Henrietta Lacks" By Rebecca Skloot. It's a bit of a dramatic take on the whole story, but definitely a wonderful read and gives a lot of emotion to the whole thing on top of the science.
Damn, what a legacy, horrible shame she nor her family till 1970 knew just how many people she helped though.
Makes you wonder how different the world would be had she not been there.
If someone is born with the same type or very similar type cells as the one in the video, would that mean they are immortal?

HeLa cells are cancer cells, basically they've shredded the safeguards that prevent cells from dividing endlessly. Honestly the video is much more vague than I think it needs to be, but maybe that's because I know too little. Anyway, telomerase (mentioned in the video) is an enzyme that prolongs the ends (telomeres) of DNA, which normally become shorter for each cell division. There's a critical size, which is why cells generally only divide up to 50 times (with exceptions of course) - cancer cells have generally developed constituent telomerase activity.
The reason why human cells generally after a few days outside the body is (iirc) because they need stimulation with IGF, "Insulin-like Growth Factor", (again, iirc) to not undergo apoptosis and kill themselves.
Edit: Basically Henrietta Lacks wasn't born with "special" cells.

It is just a sample of her cervical cancer tumor that when kept on a nutritious medium, never died
So if the person wasn't a person but was entirely a cervical cancer tumor in disguise, then yes

Basically if your entire body was made of cancer, you wouldn't live for long.
Last time i checked, over 20 tons of biomass have been created from the duplication of the cells.

Very informative, but you, like myself, overly qualify your sentences.
