I'm personally skeptical on the ability of machine learning/neural networks to fully replace humans. I think it's more likely that it will boost productivity by performing the more simple and routine tasks, but there will still be the need for human touch. People will lose jobs because now a professional will be able to do the work of 2 professionals, but AI won't do the work of all professionals.
It's definitely fascinating to see what this form of AI is able to do, but I also am skeptical about the ability for it to replace many jobs. At the very least there will be people needed to validate the output and potentially formulate what actual information/scripting/data extraction is needed to achieve the end job most effectively. At the end of the day it is often just plagiarizing information and combining many different sources to achieve it's end goal. For more up to date information it also needs feeding and much of the important data going in (e.g. news and developments) is being created by people. There will definitely be a few jobs lost to this sort of automation right now but it's hard to judge who will be most affected.
