Why do we still build and furnish homes with highly flammable materials?

Here in the Boston area, we have had a recent string of home, condo and apartment fires and numerous people have been injured or killed. We live in an age where we can put a humans on the moon and bring them back safely with moon rocks as souvenirs. We can build a super computer the likes of Watson that can actually win at Jeopardy. Scientists just succeeded in building the first single atom transistor which may lead to true quantum computers small enough to enable smart nanobot development.

Yet we still build using materials that will go up in flames if we have an electrical short, leave a pot cooking on the stove, or drop off to sleep while smoking on the couch. Even after a home burns up, we rebuild it with the same flammable materials that just failed. Why don’t we apply our technology toward building fireproof houses?
