Dear Student,

It's actually difficult to answer on this. Since these are new streams of Computer Science, people are less receptive of them & doubt whether the professors who will teach are up to the level required. Since it is a new degree, it's common for people to doubt the authenticity & question your decision. Anyhow the final decision rests on you, both of the streams are booming technologies in India. But with IOT, a lot of jobs will be generated in India. Consider talking to people from IoT background, ask them this doubt & ask them their opinion on the same issue. You can search them via LinkedIn & ask the query to people in IOT market.

Hope this helps. Thanks.
