Designers put a lot of trust into the tools to do the right thing. Someone might just want to design type and then they realize they’re actually — This is something that Jonathan Hoefler told me a long time ago — realize that you’re not working in the design industry, you’re working in the software industry.

You’re actually building a little piece of software that someone has to install on their computer and it has to work in the right way, otherwise they’re going to be calling you and wanting their money back. I think learning to program can help you learn how this piece of font software that you’re building actually works.
