Yes. You're still going to get sick though, especially if your DNA, like now, will get damaged and grow defects over time, making cancers a huge risk.

I'm just talking out of my ass but that's how I imagine it.

china has a weird ego about wanting to have the smartest high schoolers, and then when they get to college they have no pressure anymore. i think it's because research requires an element of creativity

IMO kids don't stay kids long enough anymore.

Places like China and Japan turn kids into robots. High suicide rates, high competition for a 20% improvement?
Doesn't seem worth it to me.

Why does food taste completely different when you reheat it using the oven instead of the microwave?

don't they both just heat the food up?
9 posts and 2 images submitted.
>>
It's a hole different system to imply on the fisical state of your food
>>
the heating process is completely different

if a oven, heat is beeing slowly transfered form the fire to the food by colliding particles transfering their energy to neighbours.

in the microwave, particles are bombarded by radiation, making them shake faster, increasing temperature
>>
It's going to do with the Maillard reaction. A microwave won't heat your food above the boiling point of water.

How to interpret actual curvature values beyond "positive values mean left curvatures, negative values mean right curvatures, higher absolutes mean stronger curvatures"? How to actually interpret a curvature of 2? How to interpret the difference between a curvature of 2 and a curvature of 3 in a more differentiated way than saying "it's stronger"? What does a curvature of -3.2 actually mean?

Why do all the machine learning algorithms plateau out instead of the program indefinitely continuing to improve? All the singularity / superintelligent AI scenarios seem predicated on the idea of programs programming themselves to be increasingly better at everything until they turn into magic god entities or whatever, but every single optimization strategy I'm aware of just hits a ceiling pretty quickly.

Aren't singularities and superintelligences going to be artificial general intelligences?

As far as I know, machine learning is artificial narrow intelligence.

because they dont have enough power to alter themselves, I guess?

So NASA is telling lies, faking landings, uploading CGI images and wasting money.

How come that they never officially offered us proof of (contact with) Extra Terrestrials.
Why isn't one space probe ever hijacked by aliens.
Why lie about everything else, but don't make up lies about ET?

Or are they not so full of lies as some of us like to believe?

>>9165360
I have, but...
We now know the earth is flat, so NASA lied.
We now know that all images are CGI, so NASA lied.
We now know that the moon landing was fake, so NASA lied.

If they lie to get funds, why in heavens sake haven't they come up with the lie that can provide them with unlimited funding.
Why aren't they talking about an incoming alien invasion?

Maybe they don't lie that much and did the lunar mission actually happened, are the CGI images really made by satellites and is the earth not flat at all.

Maybe I am not so retarded as you might think.
