text: I know that it may be fasinating to be able to tell anyones emotion by just using technology; t is it personal information if someone is trying to conseal being worried or mad and not have a computer tell them their emotion. "in fact, we humans perform this same impressive "calculation" every day.", i used this quote from the text to show you that yes we are capable of telling emotions as well. This technology in my opinion is not useful whatsoever because it does not show any real-world values.
