I’m increasingly convinced that being a generalist/polymath is a sure-fire way to protect yourself from Alzheimer’s and other cognitive ailments long-term (with the added bonus of living an exciting + unpredictable life!)
How do you formulate an aim in life when you don't even know what jobs will exist in a few years, or what will be invented?
You don't shoot for a specific job. You shoot for the process the job does: I want to work with the human mind, code, solve problems, fix things, etc.
