Today it's possible to buy a laser-guided sleep-o-matic superbed that walks your dog and cures your back pain. You can also buy a basic bed that's pretty nice and reasonably cheap. 15 years ago, you might have had a high-tech bed that didn't leave you sore in the morning. 1,500 years ago you had a bed of straw with fleas and bedbugs, but at least you had a place to sleep. 150,000 years you slept in furs on dirt by the fire, breathing smoke and aggravating your sciatica. Your bed was basically free, but since your livelihood depended on your full mobility, sleeping there was slowly killing you. All these beds provided the feature of "sleep." So why would anybody need a sleep-o-matic, a bed worth more in 150,000 BC dollars than the yearly economic output of your continent? Why should we accept the massive waste of resources it represents?
