Computing has gone from something tiny and specialized to something that affects every walk of life. It doesn't make sense anymore to think of it as just one discipline. I expect to see separate departments of user interface, for example, to start emerging at universities.

Elections, for their part, are typically popularity contests rather than measures of candidates' relative competency or effectiveness. Imagine if scientific truth were determined according to which scientist was most popular. To be successful, scientists would have to be charismatic and attractive - and human knowledge would suffer terribly.

Risk is the sort of word that is easy to discuss upfront but tough to handle when it comes time to pay the piper. There will always be some who wimp out and second-guess when the pain hits, but that is a childish reaction.

The idea behind a dish - the delight and the surprise - makes a difference. Great literature surprises and delights, and provokes us. It isn't just 'Here's the facts - boy meets girl, boy loses girl, boy gets girl.' It's how you tell it.

Politicians don't like to face unpleasant realities. In truth, nobody does, but as individuals, we have no choice; if we neglect to plan ahead, we are held accountable. Fail to meet your responsibilities at work, and you get fired. Ignore your car's gas gauge, and you get stranded.

Cooking is for chefs. Science informs us and lets us cook while knowing what we are doing, but it is not a replacement for the skills of a chef.

People who grow up in a region doubtless have a better cultural awareness of their own cuisine, but it's also true that a lot of locals go to McDonald's, Applebee's and the like.
