linear algebra is a part of AI but AI is not just linear algebra. I would say linear algebra is used most with machine learning with is also a part of AI.
You'll be good until we figure out how to make machines write enterprise ready software programs and the ability to maintain it on its owm. I think you have 10-20 years so you should be in management by then though so you have nothing to worry about :)
Yes, I did my research but there is no such interactive tutorial online like Treehouse or Codecademy. There are so many tutorials but none of it tells you the whole path.
Here are the resources I found useful:
==========================================
Advices from Open AI, Facebook AI leaders
Yaser Abu-Mostafa’s Machine Learning course which focuses much more on theory than the Coursera class but it is still relevant for beginners.(https://work.caltech.edu/telecourse.html)
From Director of AI Research at Facebook and Professor at NYU Yann LeCun on Quora
In any case, take Calc I, Calc II, Calc III, Linear Algebra, Probability and Statistics, and as many physics courses as you can. But make sure you learn to program.
