Honestly, there are so many different sources where you can read about How do you create a web application. You can also go to reddit. There's a lot of information there. But I would suggest you go to YouTube. Because all the information there is reliable. And personally in my opinion you can find there everything that you are interested in the development

I still don't know the first thing about it. I do want to learn it in the near future though.
I can't lookup  the links to the courses, as the wifi I'm using blocks access to The Pirate Bay. But you  can search "machine learning" in there, or you can go to Udemy.com and get the courses to watch online.
However, if I understand your post, you don't want to actually learn AI or ML, but you're looking for information about them. To the best of my (very limited) knowledge, you will get the best quality information on Wikipedia.

As far as I know, machine learning is part of artificial intelligence. The best source I can think of is Wikipedia. https://en.wikipedia.org/wiki/Artificial_intelligence

I have downloaded a number of courses on AI from The Pirate Bay (if you use it, beware of malware!), But I haven't followed them yet. In any case, the page I linked above seems very thorough. Take a look at it, and follow its sources. That should give you plenty to write about.
