Jair Ribeiro has a nice article asking us if there are careers in AI that can positively impact society. From the article:
Through Artificial Intelligence, it is possible to combat violence against women; assist lawyers, law firms, and departments with document analysis and monitoring of changes in legislation; assist clients with financial matters; make farmers have better productivity; help the elderly to have a better quality of life, among thousands of other things.
AI advancements will be no less significant. For example, AI will soon be able to accelerate drug discovery and green energy research.
