You've proved my point. Watch NASCAR and you'll see there are certain challenges that will only present themselves when you're driving 200+ mph. These can be useful to keep in mind as you are learning how to drive for the first time, but there are more immediate issues to focus on, like how to hold the steering wheel properly, shift gears, and use the gas/brake. It won't help much in the practical sense to study advanced drafting techniques at that point if you can't even pull out of the driveway, but if it helps motivate you over the long term, then that's fine. Similarly, I don't think it is beneficial to talk about switching to MongoDB and node.js because you think PHP/MySQL is slow when you haven't even learned how to add indexes and caching.
