Hi Fawaz, great article. You mentioned that pair programming 'parallelized execution' and helped knowledge spread. As a Senior Web Dev transitioning into Embedded Systems/IoT, I often find myself stuck in 'tutorial hell'—watching videos but struggling to ship actual code alone. In your experience, can pair programming help an engineer who is 'stretching' into a new, difficult domain like C or System Design, or does it only work when both engineers already know the stack?
