Why do we need Smart Toys for Kids?

The word "Smart" will probably go on to become the most popular prefix in the English language in coming years. We have had Smart Watches, Smart Phones, Smart TVs etc. for quite some time now and everytime something "Smart" comes up in the market, everyone wants to buy it. Do you remember Woody from The Toy Story? Here's a picture just to make sure. What if someone told you that in near future you could have an interactive toy which can adapt, learn and respond actively making your child's playtime amazing?
