Kelsey Hightower's 'Solve It Once' Principle and What It Means for Security

At PlatformCon 2026, Kelsey Hightower outlined a career-spanning principle: solve a problem once, encode the solution as a reusable artifact, and eliminate the manual loop entirely. He illustrated this with an early job where deployment engineers repeatedly processed Jira tickets by hand, a cycle he ended by writing a Puppet manifest that automated the entire workflow. The same pattern, he argued, explains transformative tools like Docker and Kubernetes, which did not speed up manual steps but rendered them unnecessary by identifying a repeatable abstraction. Hightower warned that mistaking faster automation for true innovation leads to building bots that accelerate old loops rather than substrates that dissolve them. He applied this lens to security auditing, where engineers repeatedly check IAM policies by hand each week, suggesting the field needs a substrate that makes those manual reviews obsolete.
