They don't but realistically that is the incentive and motivation for many people - including technologists who ultimately decide to use their understanding of the market to leverage capital rather than code or perform a similar technical function. In your case one could argue that if you saw so much future value in the Mac/Apple ecosystem you missed out significantly by not purchasing Apple stock. Depending on when you made your observation, even a modest investment would have had a significant return over the past 20 years. I actually use the Amazon example when people tell me how worried they are about Amazon becoming all almighty and taking over all commerce - that if they actually believe that then they should probably buy Amazon stock and use the profits to do something to counter whatever negative effect they perceive. As a former software engineer and founder now VC what I personally realized is I could have the greatest impact on the industry from leveraging capital around my own industry thesis rather than continue to build it myself. It's all a layer cake.
