text: Praticality also remains an issue for would-be-users of this technology. As D'Alto writes, not everyone's "home PC [can] handle the complex algorithms used to decode Mona Lisa's smile" (and subsequently their own). Many would be unwilling to buy a more powerful PC simply to allow the facial analysis software to work. While most, if not all, people acknowledge that education is important, powerful PC's often cost over one thousand dollars, a price that many are unable or unwilling to pay for a convenient online education. Also, there remains the issue of the technology itself. How would it be distributed? Would it be software or would it be built into computers? Would there be a price tag attached? These are all questions that affect how practical this technology is. Imagine people empty their wallet of a couple thousand dollars only to find that the algorithm only comes preinstalled on certain computers, or is incredibly buggy and doesn't work properly. People might argue that users should educate themselves on how the system works before even considering buying the product, but often, for products like this, the information is woefully incomplete or exaggerated. Until the technology can become accessible to the average everyday user, it will fail to successfully be implemented in online classrooms.
