Social Development (Morris) - 🧠 ANSWER ✔✔A group's ability to master its
physical and intellectual environment to get things done over time
The Steam Revolution (Morris) - 🧠 ANSWER ✔✔- The industrial revolution
marks the biggest/fastest transformation in human history
- Allowed us to overcome the limitations of muscle power, human and
animal, and generate massive amounts of useful energy at will
,The Second Machine Age - 🧠 ANSWER ✔✔Computers and other digital
advances are doing for mental power (the ability to use our brains to
understand and shape our environment)
- What the steam engine and its descendants did for muscle power.
The 3 "broad conclusions" the author made - 🧠 ANSWER ✔✔- We're living
in a time of astonishing progress with digital technologies - Ones that have
computer hardware, software, and networks at their core (not brand new,
but have refined our digital engines)
- The transformation brought about by digital technology will be profoundly
beneficial ones - Increases variety and volume of our consumption
- Digitalization is going to bring it with some thorny challenges (economic
rather than environmental disruption and replacement of workers with
computers)
There's never been a better time to be one kind of worker, and a worse
time to be another - 🧠 ANSWER ✔✔There's never been a worse time to be
a worker with only ordinary skills and abilities to offer because computers,
robots, and other digital technologies are acquiring these skills and abilities
at an extraordinary rate
,What computers are good/bad at - 🧠 ANSWER ✔✔Computers are good at
following rules:
- Information processing tasks
- Algorithms are simplifications; they can't and don't take everything into
account include the most common and important things
- Predicting payback rates
Computers are bad at pattern recognition:
- Information processing tasks that can't be boiled down to rules or
algorithms (no human capacity for pattern recognition)
DARPA and story about the car - 🧠 ANSWER ✔✔- Defense Advanced
Research Projects Agency
- DARPA Grand Challenge for driverless cars:
Built a completely autonomous vehicle that could complete a 150-mile

- The possibility of exchanging information with a computer rather than
another human is a long way off
Siri's troubles - 🧠 ANSWER ✔✔- If it didn't understand what was said, it
would ask for repeated clarifications and gave strange or inaccurate
answers
- ex: Where is Elvis buried? Could not answer because it thought the name
was "Elvis Buried"
Tom Mitchell's claims (Carnegie Mellon) - 🧠 ANSWER ✔✔"We're at the
beginning of a ten-year period where we're going to transition from
computers that can't understand language to a point where computers can
understand quite a bit about language"
Computers' communication abilities compared to humans - 🧠 ANSWER
✔✔- Natural language processing software is still far from perfect, and
computers are not yet as good as people at complex communication
- Computers' communication abilities are not as deep as humans', but are
broader
