Specialization only works if things don’t change – and things always change. The more you focus on developing any single skill, the less time you have to develop other skills that can help you in the event things in your environment change unfavorably.
A person who only knows how to do one thing exceptionally well is on solid ground for as long as that skill is in high demand, but if the environment changes to make that skill unnecessary or undesirable, they’ll have more trouble adjusting to the new situation. The very best high-rise architect in the world is screwed if no one wants to build skyscrapers anymore.
