Animals see a video of the world. If an animal were only to see still images, how would its vision develop? Neuroscientists have run experiments in cats in a dark environment with a strobe so it can only see still images - and those cats' visual systems actually underdevelop. So motion is important, but what is the algorithm?

You want to evaluate future borrowers, but in order to train an algorithm that will help you identify future defaults, you have to train it and evaluate it on past data.

We sell in Moda Operandi, which, if you don't know what it is, it's a beautiful luxury site that does pre-trunk shows for designer collections. We got them to change their algorithm online to go up to a size 24.

I helped start a ceramics company called CPS Technologies. We took it public in 1987 at $12 a share. Three months later, there was this horrible cliff: Black Monday. Fidelity had bought 15 percent of our stock, and their algorithm caused them to dump it all onto the market that day. We dropped from $12 to $2.

The world of online marketing, where HubSpot operates, though, has a reputation for being kind of grubby. Our customers include people who make a living bombarding people with email offers or gaming Google's search algorithm or figuring out which kind of misleading subject line is most likely to trick someone into opening a message.

The first brand that can purpose-build great stories for mobile, that can target in a relevant but noncreepy way and understand that it's the individual that matters, not the algorithm, is the first brand to win mobile and, possibly, the future.

Programming is the art of algorithm design and the craft of debugging errant code.
