Did Futurama (1999) just predict the future?

No but they did a good job predicting the present

I like how two of them just say "VOMIT"

What future? The internet was very much there in 1999 and it was full of ads. Wasn't that about the time they came up with epilepsy-inducing animated ads in nauseating colors? I remember when people thought it couldn't get any worse.
