i'm a tech generalist. i get bored easily, so i know a bit of everything. i'm good at architectural roles, but not deep dives. i've been invited to speak at a conf, but i have no idea what to talk about! what would you want to hear from someone who's scratched every surface?
Don't try to get abstract just because you're a generalist. Stay concrete. Talk about something that got you excited recently, and your experience digging into it.
