Hyper-typing in TypeScript is where libraries strive for perfect type safety but create overly complex and difficult-to-understand types.

WHY THE APPLE II DIDN'T SUPPORT LOWERCASE LETTERS

Steve Wozniak, being financially constrained, initially used an affordable $60 uppercase-only keyboard for his TV Terminal project in the early 1970s.
