I agree, bobbym. However, I look at it slightly differently. Extinction for us will probably be from a lazy researcher who says "whoops."
What I don't understand is why prices are so high for so many things that have become heavily automated, like cars or milk. Also, why are we paying $2-3 for boxes of dried starches? Half of stores are made up of variants of that, seems completely stupid.
If you had to use binary, decimal, and floats all at the same time, you might come up with sqrt(4)-2=-8.1648465955514287168521180122928e-39 as well. Notice the sqrt(1)-1 is fine. Personally I prefer to use the Google Dual-Mode Calculator app in Google mode, which gives sqrt(4)-2=0.
I'm a CIS student (hopefully still) at Saint Leo in FL. If I do start an online app company after I'm done, then obviously math. However, I'm not here because of that. I'm here because I feel I have a better understanding of math now and have relaxed a bit since I essentially have a professor with me wherever I go, aka the internet and a pc. I feel I have something to add, too.
