Not at all. You can still learn about blockchain. Jokes aside, you don't have to learn AI/ML specifically to remain relevant, but you have to learn something.

Not at all. You can still learn about blockchain. Jokes aside, you don't have to learn AI/ML specifically to remain relevant, but you have to learn something. You can learn: - about a domain (energy, finance, medicine) - a toolset (math, stats, programming, design), - a "hot" new technology (bitcoin, drones, wearables, VR), - put together a network of talented people and so on. You have to do something, but not necessarily any particular thing.
