I used to fear specialization because of a form of commercial or career FOMO. The reality is you instead get spread to thin and are (ironically?) now at risk of being displaced by "good enough" AI solutions. If you are a generalist you still need to be "T-shaped" with a few areas of deeper expertise. Funny enough your expertise could be getting things done-done using all your generalist abilities (ex: able to take initial ideas all the way to a active, viable business).
