I don't think the average consumer has much of a need. Industry and government does. IoT sensors on infrastructure such as lamp posts could make bulb replacement easier to track. Same with various machines. You can track health and productivity for better maintenance. Some might like the convince of an IoT device like the Echo. That's a personal choice. Properly developing both sides of the device spectrum should improve quality and security.
