You tell the "For you" algorithm 20 times you want to see fewer posts from someone and it retaliates by flooding you with them.

@drhingram Went to a Jerry Sadowitz gig and the average age was 50+
When Gen X is gone, we're gone, but we'll be cantankerous old gits for a while yet.

@SarahCholwill @Alexdaftie No nagging, no expectation to be a mind reader and toilet seat left up.

@rastokke "What is x?"
"x can be anything."
"How can something be anything?"
The kids who don't get that won't benefit from any more maths teaching.
Maths isn't for everyone, why should it be?
Just make sure they're able to count.

@wattsupwiththat The End is Nigh mob have always been with us, projecting their individual mortality onto the planet.
The earth isn't dying, they are.
It's their time that's running out.

@MKWPublishing Calendrical age is just the number of trips around the sun.
Entropy is the real measure of aging but you can dump it on the fly, when no one's looking, just don't get caught, there are laws against it.

@AndrewZywiecMD Words matter.
If people had been told to inject "alien genetic code" they would have baulked because they saw Jeff Goldblum turn into a fly.

[Superman @thesupermannx]

Researchers wired a piece of dead human brain to a robot.. and it learned to play piano.

they took an adult human brain explant (yes, dead brain tissue), kept the neurons alive in a dish, and hooked it up to an anthropomorphic robotic hand equipped with a microphone.

they didn't use backpropagation. they didn't train a silicon neural net. they just let the biological brain tissue listen to the sounds of piano notes while the robot pressed the keys.

through pure unsupervised sensory-motor learning, the disembodied brain tissue mapped the audio frequencies to the physical motor movements.. and then it started controlling the robot hand itself to imitate the human piano playing it heard.

the brain tissue retained this new "memory" and bi-directional plasticity for several days.. it only stopped when researchers actively disrupted the electrical neurotransmission.

this is a massive leap for hybrids. we are moving past artificial neural networks and straight into using literal human neurons as biological processors for machines.

the line between biology and artificial intelligence is disappearing..
