Headlines, in a way, are what mislead you because bad news is a headline, and gradual improvement is not.

It's possible - you can never know - that the universe exists only for me. If so, it's sure going well for me, I must admit.

I'm an investor in a number of biotech companies, partly because of my incredible enthusiasm for the great innovations they will bring.

The idea that you encourage companies to take their innovative thinkers and think about the most needy - even beyond the market opportunities - that's something that appropriately ought to be done.

Considering their impact, you might expect mosquitoes to get more attention than they do. Sharks kill fewer than a dozen people every year, and in the U.S. they get a week dedicated to them on TV every year.

If you have 50 different plug types, appliances wouldn't be available and would be very expensive. But once an electric outlet becomes standardized, many companies can design appliances, and competition ensues, creating variety and better prices for consumers.

You can't have a rigid view that all new taxes are evil.

What destroys more self-confidence than any other educational thing in America is being assigned to some remedial math when you get into some college, and then it's not taught very well and you end up with this sense of, 'Hey, I can't really figure those things out.'

One thing I've always loved about the culture at Microsoft is there is nobody who is tougher on us, in terms of what we need to learn and do better, than the people in the company itself. You can walk down these halls, and they'll tell you, 'We need to do usability better, push this or that frontier.'

Now everyone takes it for granted that you can look up movie reviews, track locations, and order stuff online. I wish there was a way we could take it away from people for a day so they could remember what it was like without it. 

Teaching's hard! You need different skills: positive reinforcement, keeping students from getting bored, commanding their attention in a certain way.

I've always been amazed by Da Vinci, because he worked out science on his own. He would work by drawing things and writing down his ideas. Of course, he designed all sorts of flying machines way before you could actually build something like that.

If you go back to 1800, everybody was poor. I mean everybody. The Industrial Revolution kicked in, and a lot of countries benefited, but by no means everyone.

Even with cameras being very cheap, one thing that researchers noticed was that you look really bad in a videoconference image because the lighting is bad and you get shadows and things.

The most impactful dollars that Australia can spend are actually what goes to help the poorest.

I understand how every healthy child, every new road, puts a country on a better path, but instability and war will arise from time to time, and I'm not an expert on how you get out of those things.

The next time someone tells you we can trim the budget by cutting aid, I hope you will ask whether it will come at the cost of more people dying.

Outlook 2003 did create the idea of search folders and the whole Longhorn philosophy. You can see it at work in search folders, where instead of having to drop things into individual folders, and things exist only in one folder, you create these search folders and you have the criteria for the search folder.

There's always been a lot of information about your activities. Every phone number you dial, every credit-card charge you make. It's long since passed that a typical person doesn't leave footprints.

The difference between a stranger sending you a message that you might be interested in at a very low volume level, no repetition, just sending it to very few people, and that being done as spam - those things get close enough that you want to be careful never to filter out something that's legitimate.

By the time we see that climate change is really bad, your ability to fix it is extremely limited... The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while. 

Should there be cameras everywhere in outdoor streets? My personal view is having cameras in inner cities is a very good thing. In the case of London, petty crime has gone down. They catch terrorists because of it. And if something really bad happens, most of the time you can figure out who did it.

People want to watch whatever video they want to watch whenever they want to watch. If you provision your Internet infrastructure adequately, you can do that.
