What everyone seems to be missing is that we already use the 3 laws today. Sure, they're not enumerated as such, but we use those principles in modern machinery already. Automobiles, airplanes, construction equipment - they all use some variation of those concepts in their construction and operation:

There are quite a few plants alive today that are far older than 1500 years . . . individual specimens can be up in the 4-5000 year old range.

It's rare to see negative portrayals of large cities on television or in the movies.

Road Surface Layer - translucent and high-strength, it is rough enough to provide great traction, yet still passes sunlight through to the solar collector cells embedded within

It's made by NuytCo who made the newt.

There were probably Steller's seas cows - one of those would keep a small group going for a while. Anyone who'd spent generations in Beringia probably had some techniques for hunting marine mammals.

You didn't want to be within a hundred miles of that procedure.

This reaction works well without the salt; the baking soda alone should do the trick. It also works on several other alloys, but I don't have a list handy. I've been using this method for years.

Yes, you can liberate plenty of hydrogen with enough of the materials, and I know that experimental hydrogen-generating rigs…

They're hard to get one's hands on sometimes. But they're really terrific.

Well said: It's not that science, tech and SF are inherently optimistic OR pessimistic; it's the people who bring it to us, and their take on it.

Just wait until the next hot summer, then the South can laugh at the northerners stripping in the streets and buying overpriced fans on the street because the temp exceeded **80**. God help them if they get 30+ 100 degree days like parts of the South!

Yea, I was going to mention that he must not have seen, Soylent Green, Planet of the Apes, Logan's Run, A Boy and his Dog, Mad Max, etc.

"...this was the first movie to really speculate that the future flat out sucks"

If by arrogance you mean the callousness with which the US inflicts suffering on countless millions around the world and by nutjobs your various leaders, then yes.

Error bars! We need error bars!

I was thinking the same thing. How granular is the data? Do women in male-dominated professions score closer to the average male than the average female? Or vice versa for men in female-dominated professions? Are the gender differences between older individuals more pronounced than younger individuals? These are just…

Well, any time it's been investigated in the past, individual differences have accounted for a much higher proportion of the variability than group difference (e.g. differences between two people of the same sex or race are much greater than the differences between the sexes or races).

I'd imagine individuals within a sex vary far more than the average male varies from the average female depicted in this study. But that's just a gut reaction.

No, it really is difficult to interpret. Connectivity changes frequently and is dependent on environment. People with mood disorders who undergo treatment will have wildly different connectivity before and after treatment. This study tells us very little about what is intrinsically different about men and women, but…
