I'm pretty sure that's a typo. It's gotta be +100°C to -90°C at least. I mean, my skin is designed to protect me above 100°F.
As for Jeremiah Weed, he's just a troll with no imagination or dream of science. John Atanasoff invented the first digital computer (at Iowa State University I might add) in the 1930s. Since then we've gone to the moon. By Jerry Weed's logic, we shouldn't continue to press the limits and find better ways of doing computing. I bet he likes his smart phone though. Either way, what the hell does it matter to Weed? It's not costing him any money and if the dude makes a 10 foot deep hole in the ground, it's not Weed that dies. Stop feeding the troll.
