The machine didn't learn anything, just executed your orders.
Imagine that you sit with your grandma in front of a PC (and let's assume she's not a SE). You fire up a terminal, give her the keyboard and dictate every keystroke necessary to write and execute a program (or do any other task for that matter). Does that mean that your grandma just learned programming? I think not. Learning implies being able to find and apply some rules which where not explicitly given.
This is not backed up by any data, but for me the experience on Chromium based browsers always seems faster and smoother, especially on modern, JS heavy sites.
Also, I'm a sucker for feature rich applications and I really like how much stuff Vivaldi and Brave have built-in. This is extremely subjective though and I know there are many people who consider all of this a terrible bloat.
