I don’t know why everyone doesn’t have one. If it’s an issue of not wanting to spend the money, sure. I get it. There’s a long list of really sweet motorcycle gear I’d have in a heartbeat if I had the money. I’d also probably have a belt-fed grenade launcher mounted to the hood of my blacked-out turbo-charged Subaru XV super car. If you’ve bought any mattress or bed in the past five years and not gotten some form of memory foam, you’ve opted for antiquated and obsolete technology, and you’re sleeping less comfortably than you know.
Things change, science moves forward, and we make better things. Traveling minstrels were replaced by sheet music and resident pianists, who then competed against the phonograph and records. Radio was usurped by television, which later had to adapt to the advent of cable tv, which scrambled to remain relevant because the internet offered more targeted content, that’s available when we choose to watch it. I don’t know what’s next, but odds are it will be better than what we have now. Things move forward, progress happens.
On a side note, this is why I don’t understand the people who can’t grasp the concept of evolution; one can see it happen on a daily basis. Things evolve all the time. There were other less convenient ways of listening to music before the iPod, you just weren’t around to see it. In a way, cassette tapes are the Piltdown men of the music world. They were smaller, more portable ways of listening to music. If Siri were a fundamentalist Christian she’d be yelling, “I didn’t evolve from no phonograph!!”
People, animals, and plants do the same thing, we just do it at a much slower pace than electronics. Genetics knows not to make too many drastic adjustments too quickly, it takes it’s time. Things also weed themselves out of existence; think of how many car companies have gone under because they refused to adapt to changing market environments.
At some point people gave up their hay filled sack for metal coils and padding. Every advance was met with the same reluctance to change. I guarantee that someone in the 1700’s refused to get a wool and cotton filled mattress, because they thought there wasn’t anything better than a good old sack of lice and hay. I don’t know what’s going to come after memory foam, but I’ll be game to give it a whirl too.
