This process forces a "slow tech" mindset. In a lifestyle dominated by the dopamine hits of social media and 15-second entertainment clips, sitting down to orchestrate a multi-gigabyte database installation requires patience and focus. It is a return to a time when computing was a craft, not just a utility.
