When Computers Have Brains

Future Rise Newsletter #39 | Nov 4th (2025)

Scientists at Johns Hopkins and other labs have just done something
remarkable. They've grown tiny living brains in a lab that can
actually learn. These organoids are clusters of around 100,000
human neurons grown from stem cells, each no bigger than a pea, yet
capable of astonishing feats.
In one study, researchers wired these brain cells to a computer running
the video game Pong. Within five minutes the cells figured out how to
move the paddle with no programming, no code, just trial, error, and
adaptation.
This is a new field called biocomputing where living brain tissue
performs the computing instead of silicon chips. The potential is
staggering. Your brain runs on about 20 watts which is less than a
light bulb while supercomputers need around 21 million watts to
approach the same capacity. Humans can learn a skill from just ten
examples while A.I needs millions.
The benefits of this development could be revolutionary. Energy
efficient computers that learn like humans, adapt in real time, and get
smarter without vast data centers.

Takeaways

1. Biocomputers could outperform A.I and supercomputers in efficiency
and learning speed.
2. The technology could drastically reduce energy demands for
advanced computing.
3. Ethical debates about consciousness in lab grown brains will become
unavoidable.

Actionable Insight

These tiny biocomputers run on just 20 watts which is less than a light
bulb. This is a powerful metaphor. The leaders who will thrive aren't
the ones who burn out chasing growth; they're the ones who use their
energy wisely. Calm. Focused. Intentional.

Until next time...keep future rising
