Remember your first day driving without your instructor? Were you able to think about the optimal path through the city or were you focused on shifting gears and handling all the stimulus you were facing? The same happens when driving IntelliJ. It's just that you didn't know that you're driving a Bugatti!
The purpose of this presentation is to showcase some tricks that will improve your code writing speed. But let's make it clear: the goal is not to finish the work faster. No. But to be able to explore a design idea or some refactoring without investing precious time and/or emotional involvement. Victor wants to help you to become faster to feel less guilty when you throw away some experiment, so you can then find the most simple design to solve your problem.
