Frightening
AI is already being applied
in many fields. People can
use AI to help them drive
vehicles. Write novels,
translate foreign
languages and do many
other things. From this
points of view, AI can be
friends with humans.
The benefits of AI also bring concerns and fears.
Could machines really develop human-like
intelligence And what would happen if they did
Would thinking machines work alongside humans
or threaten the existence of humans How would
they be punished if they committed crimes or
even murdered humans As we become more and
more dependent on computers, we should think
about the dangers posed by the advances in AI.
Therefore, the development of AI could also be
frightening.
Read the popular science article again carefully and answer the following questions.
A2
1. How can a deep-learning machine improve its own performance
By learning from the results of its previous actions.
2. What events were considered as major breakthroughs in Al
Deep Blue beat the world chess champion Garry Kasparov in 1997, and AlphaGo defeated Ke Jie, arguably the best human Go player, in 2017.
