Quantum computation is a distinctively new way of harnessing nature. It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes.

If you can’t program it, you haven’t understood it.
Interpretation
True understanding of a concept is proven by one's ability to implement it practically.
David Deutsch's quote emphasizes that comprehension of an idea is not merely theoretical but practical as well. If one cannot translate a concept into a program, it signifies a lack of deep understanding of that concept, as real mastery enables one to apply knowledge effectively in real-world scenarios, particularly in the field of technology and programming.
In practice
In a tech seminar, to emphasize the importance of hands-on experience, one might say, 'Remember, if you can’t program it, you haven’t understood it.'

Science is objective. And in my view we cannot take any experimental results seriously except in the light of good explanations of them.
Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow.
Discovering a new explanation is inherently an act of creativity.
To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.
Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests.
[Concerning] the usual contempt with which an orthodox analytic group treats all outsiders and strangers ... I urge you to think of the young psychoanalysts as your colleagues, collaborators and partners and not as spies, traitors and wayward children. You can never develop a science that way, only an orthodox church.
There are people who could watch a hurricane like Sandy blow out of the Atlantic every other day and blame it on anything but human activity. They are like those who, having been diagnosed with diabetes, eat donuts for breakfast. There's not much to do about them.
If the Sun exploded, we wouldn't know about it for 8 minutes and 20 seconds. Light and gravity take that long to reach us. Then we would vaporize.
It is shameful that there are so few women in science. [...] In China there are many, many women in physics. There is a misconception in America that women scientists are all dowdy spinsters. This is the fault of men. In Chinese society, a woman is valued for what she is, and men encourage her to accomplishments yet she remains eternally feminine.
The real value of science is in the getting, and those who have tasted the pleasure of discovery alone know what science is. A problem solved is dead. A world without problems to be solved would be devoid of science.
Eventually we must leave Earth-at least a certain number of our progeny must as our sun approaches the end of its solar life cycle. But just as terrestrial explorers have always led the way for settlers, this will also happen extraterrestrially. Earth is our cradle, not our final destiny.
