In 2016, the Mirai botnet hijacked roughly 600,000 IoT devices and knocked major websites offline. Here's my framework: safety means physical, privacy, and digital security combined. Smart home devices add convenience, sure, and the other side is right that a doorbell camera can deter someone. But the core problem is attack surface. Every connected lock, bulb, or thermostat is another poorly patched computer on your network. One breach can unlock doors, disable alarms, or spy on you. A safer home shouldn't depend on trusting dozens of cheap vendors forever. That net risk makes us less safe.
