File this idea under the category of “what could possibly go wrong." Amazon is apparently in talks with a startup to deliver packages to the trunk of your car and the inside of your home – while you are not there.

Amazon, of course, also floated the idea of using drones to deliver packages. The company tested the concept last year, which was met with obvious challenges.

The world of tech is about taking seemingly unfathomable ideas and making them indispensable to everyday life. Amazon, after all, has revolutionized commerce. But the line between innovation and dumb is fine. Remember the spectacular rise and fall of Juicero, the $400 internet-connected juicer?

What are some of the dumbest tech ideas you have heard? What seemingly dumb tech ideas that have actually succeeded?
