When you start using a new tool, there is a separation: it’s you and the tool; you use it, learn how it responds to various stimuli.
Over time, your brain has FPGA-like abilities and wires up some specialized circuitry. To you, it feels like you and the tool are now one thing. Your brain controls the tool like it’s an extension of your body.
Riding a bike, playing chess, even reading and writing can be viewed through this lens.
Your brain is amazing! Use it!
