is artificial intelligence mL is hard to learn
I would say, AI and ML isnt as difficult to learn, but more difficult to apply for the right process optimization and applications. You should perhaps first start with Python, learn concepts of Data Sciene and ML, followed by couple of strong Projects and Self Learning. Once youre confident with this Section, I believe youre good to go with Deep Learning and AI in future, with relevant Certifications, Projects and Internships. COURSERA AND UDEMY are really valuable platforms which help you with these technologies.
