Without a doubt, the fields of AI and Machine Learning have become popular. Exposure to such fields is widely available but insight on where these fields are going is something that is not always present with novices to the field. I have compiled a short list of influential people in these fields and their twitter handles:
Fei-Fei Li, 
Andrej Karpathy, 
Ian Goodfellow, 
Guido van Rossum, 
Francois Chollet, 
There are many more but this is a good starting point. I hope you follow these people and take advantage of their insights.
