School? School.

GM- We go to school since we wouldn't choose to learn by ourselves. We'd just sit around since there would be no one to force us to be productive. And besides, many businesses don't take homeschooled people as seriously a school-educated people.
 
RF- I realize the thing is trying to be funny, but it has such a careless air of stupidity that it really just shows how much we need school/some kind of formal education.
First, like GM said, few people will actually buy a globe or watch Dora. Now YouTube, sure, but again, most will not bother to delve into music genres beyond pop.
Second, all those arguments are not true. I already briefly mentioned the music thing. YouTube has a lot of amazing content, but its ability to teach you how to play an instrument is not nearly as good as a real human. If by music, you mean music history, YouTube has stuff, but will you really go look it up? Wii can be a substitute for exercising in the traditional ways, but you are still spending time in front of a screen, which you would have already done for hours on YouTube for you "music" "education." Also, who's going to require you to play Wii?
On to Spanish. From my experience, Dora uses few Spanish words. After watching Dora, you will probably know how to say hi, bye, let's go, jump, and the names of a couple animals. How helpful will that be in communicating? You can't even ask where the bathrooms are! It's kind of the same in English. You can't communicate with only the phrases "laughing out loud," "be right back," and "I don't know." Although, if we really stopped having school, "IDK" might just suffice for most situations.
In math, having a calculator does not make you able to do math. If you don't know what numbers to put in, how is any answer going to appear? As for geography, globes are nice, but not the most detailed things ever. Also, who would actually buy one? Last, but certainly not the least incorrect one, is the argument for history. History is not dead. The effects of the events in the past are still in our present. Learning about the past helps us understand the present. Furthermore, you are part of history. Would you like the future people to just say, "Well, they're dead, so it's not like they ever mattered." Learning history helps you remember there were people before you, and there will be more people after you. We will eventually all be gone, with no one to remember the great works of anyone, but I think we should remember because we can and owe it to those who before us.

In conclusion, yes, we need education!
