Perhaps we'll see a future that's fully automated, one where artificial intelligence does absolutely everything.
But until then, we'll live in a world where most physical tasks are accomplished by human gruntwork. In general, we're up to the task. But sometimes, things don't work out quite as intended.
Feel free to have a chuckle over these terrible ideas and terrible designs, but consider the fact that bad ideas are, in a sense, what makes us all human.
