If Cars Were Computers…

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


800px-SSEM_Replica.jpg If cars were computers then one liter of fuel would provide all the UK’s needs for one year and oil reserves would last the expected lifetime of the solar system. That is, if efficiency in cars had improved at the rate computers have. This according to Steve Furber, a computer engineer at the University of Manchester, in a lecture marking the 60th anniversary of the 1948 computer known as The Baby (also known as the Small Scale Experimental Machine). Furber notes that computers are now 50 billion times more energy-efficient than The Baby, which weighed a ton, took up a whole room, and was the forerunner of all modern computers.

I’m not sure we can shrink cars & their carbon footprints fast enough. Howzabout we shrink ourselves instead? Genetic engineering trumps computer engineering and nine billion teensy weensy people 42 years from now doesn’t look so bad. No worse than a swarm of locusts.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
