We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Our minds work in real time, which begins at the Big Bang and will end, if there is a Big Crunch - which seems unlikely, now, from the latest data showing accelerating expansion. Consciousness would come to an end at a singularity.
Interpretation
What this quote means
The quote reflects on the nature of time, consciousness, and the universe's expansion, suggesting a beginning and potential end of existence.
Stephen Hawking's quote delves into the concept of time in relation to the universe, positing that our understanding of consciousness is intertwined with the cosmos and its fate. He highlights that while our minds operate in the continuum of time that began with the Big Bang, the accelerating expansion of the universe makes a 'Big Crunch'—a reversal leading to a singularity—less likely. This suggests that consciousness, as we know it, exists within an ever-expanding temporal framework, and raises profound questions about existence and its cessation.

It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.
In my opinion, there is no aspect of reality beyond the reach of the human mind.

Future generations will wonder in bemused amazement that the early 21st century's developed world went into hysterical panic over a globally averaged temperature increase of a few tenths of a degree, and, on the basis of gross exaggerations of highly uncertain computer projections combined into implausible chains of inference, proceeded to contemplate a roll-back of the industrial age.
Science is the acceptance of what works and the rejection of what does not. That needs more courage than we might think.

When I wrote 'Neuromancer', I had a list in my head of all the things the future was assumed to be which it would not be in the book I was about to write. In a sense, I intended 'Neuromancer', among other things, to be a critique of all the aspects of science fiction that no longer satisfied me.

The history of acceptance of new theories frequently shows the following steps: At first the new idea is treated as pure nonsense, not worth looking at. Then comes a time when a multitude of contradictory objections are raised, such as: the new theory is too fancy, or merely a new terminology; it is not fruitful, or simply wrong. Finally a state is reached when everyone seems to claim that he had always followed this theory. This usually marks the last state before general acceptance.
