The transition from a robotic hand that grasps a ball to a hand that grasps a apple is not a simple specialization; it's like comparing managing a basic savings account to managing a complex options portfolio in the stock market.
Both are forms of asset management, but the latter requires a fundamental understanding and tools that are different to manage volatility and risk.
For an apple, sensors that detect variable pressure and algorithms to adapt to its irregular shape and fragility are needed, thus avoiding turning it into applesauce.
If you manage stable government bonds, you don't need the same protections and hedging strategies as for speculative stocks that can collapse at any moment.
