“People who are really serious about software should make their own hardware”

Simplified Meaning:

If someone wants to create amazing programs, they should also build the devices these programs will run on. This idea is like a chef who not only prepares delicious meals but also grows their own vegetables. By doing both, the chef ensures the ingredients are perfect and the meals are even better. Similarly, a software developer who makes their own hardware can design it to work perfectly with their software, leading to a smoother and more efficient experience. This combination of skills can result in better products because the person understands how both parts work together. For example, by controlling both the hardware and software of a smartphone, a company can create a device with unique features and better performance, much like Apple does with its iPhones.
