Everything we say to computers can be expressed in ones and zeros. On or off. Open or closed. Yes or no. Humans have many more options with which to communicate, but the concepts of “Yes” and “No” are still two of the simplest, most important units in our languages… and yet – sometimes – two of the most difficult to use confidently. This talk is a meditation on communicating commitment and consent; on the impact these two small words can have in our relationships with our work, our time, our colleagues and clients, our loved ones, and ourselves.
