Learning Artificial Intelligence in 2018

You need to clarify for yourself what AI means to you. Most companies use it as a buzzword so they can sell more. Generally any valuable research in AI requires a lot of data, time, and money. Majority of companies in the world can't afford that (which is why Facebook and Google manage to kinda monopolize AI fields). So most companies that you'll come across that mention AI or Machine Learning, won't actually be using proper AI or ML. They'll just mean they need a developer who knows how to play with available AI libraries and tools.
Conclusion: to become an AI engineer that the industry in Malaysia will respect, you can watch some tutorials and complete some online courses and play with some APIs and libraries, and in the course of 6 months or one year, once you master all of it, you can get a job as ML engineer and increase your salary by several thousand bucks a month.

If you wanna learn AI to push the human race forward, by searching for cancer cure using AI, working on personalized education, fixing major problems in economy that humans are unable to solve etc, you're gonna need more than good programming and maths skills. Those are important (and probably necessary for the beginning) but most importantly you'll need a great understanding of (or be familiar with) some or all of these:
leadership, human civilization, psychology, economics, biology, philosophy, physics, behavioral science and more. There've been thousands of AI researchers, creating valuable mathematical research, but have all of them contributed significantly to the progress of human race? Nope.

Traditionally, here are a list of things to learn to learn AI https://metacademy.org/browse
I'm not in a rush to learn these concepts because I think there's more to achieving human level intelligence in machines than just learning maths and programming. So I'm being patient and growing all aspects of my knowledge, from CS and maths to humanities and other sciences. Next time you ask someone "how to learn AI/ML", ask yourself "do I wanna solve a long-term problem in the world or do I wanna get a decent job?" Both of these are respectable and valid options, but one of them is significantly harder than the other!
May God help all of us in our AI endeavors!
