"What makes us think we can shove groomed, specialized data into our crude machines for a /few hours/". Because we can scale out the machine learning process. For humans, it's a sequential trial and error process, one learning episode at a time. A machine can scale in parallel 1k or even 1M learning episodes, literally cramming years if not life-times of learning into those /few hours/.
