Let's Stop Making Each Other Feel Stupid

This is the slide deck from PulpoCon, September 2025.

We work in an industry where we have to prove how much we know. And yet, there are a million different paths through software development. On a day-to-day level we have to specialise on one task at a time.

The skills we don’t need now are necessarily forgotten, or delegated to someone else. And that’s fine. Instead of judging people for their ignorance, let’s help them to feel excited about all the new things they’ll discover. Instead of saying “How come you don’t know that?” let’s say “Fantastic! Lucky you. You get to learn something. What can I do to help?”

Sign the manifesto:
