무선 vs 케이블의 미래

## The Current State

Wireless has improved dramatically:
- **Wi-Fi 7**: Up to 46 Gbps theoretical (320 MHz channels)
- **Bluetooth 5.4**: LE Audio with better quality at lower power
- **WiGig (802.11ad/ay)**: 60 GHz wireless at multi-gigabit speeds

## Where Wireless Wins

- **Convenience**: No cable management, easy device switching
- **Mobility**: Laptops, phones, tablets, wearables
- **Headphones**: AirPods/Galaxy Buds have replaced wired for most people

## Where Cables Still Win

- **Latency**: Wired is ~1ms vs wireless 5-20ms (gaming, music production)
- **Reliability**: No interference, no dropouts
- **Power delivery**: Can't wirelessly charge a laptop at 140W (yet)
- **Bandwidth for video**: 8K@120Hz needs 80 Gbps — wireless isn't there
- **Professional audio/video**: Zero-latency monitoring is non-negotiable

## The Verdict

Cables won't disappear. They'll become fewer (one USB-C cable for everything) while wireless handles the casual connections. The future is hybrid.
