The Other Side of Complexity

Oliver Wendell Holmes tols us that while simplifications on this side of complexity are worthless; simplicity on the other side can be priceless. But getting there means entering the mess, learning what matters, then clearing the rest away.

Have we seen enough mess to clean up AI? Perhaps. Richard Sutton's "Bitter Lesson" offers the most complex path. Sutton says that scale wins — more compute, more data, always better. That works if you can afford it. Software engineering can't. Labels cost hours to days. An $800B gap yawns between AI revenue and datacenter bills by 2030, and the text that trained today's models runs out before the bill comes due.

So let us walk through the mess. Across 120+ real SE tasks, a minimal toolkit called EZR — 500 lines of Python, no deps, under 100 labels, under 10 parameters — performs as well or better than SMAC, TPE, and the heavyweight crew at a fraction of the cost. Not by being cleverer. By doing less, harder. Active learning picks informative rows. Naive Bayes sorts best from rest. A 20 line tree shows what matters. The other 990 variables out of 1000 get thrown away. They never mattered.

That's the other side of complexity. Earned, not assumed.

Tim Menzies (NC State; prof, phd,)
ACM / IEEE / ASE Fellow
EIC of ASE journal

Bio

Prof Menzies earned his Ph.D. in Computer Science from UNSW (1995) and am is now a Full Professor at NC State University, where he directs the Irrational Research Lab (mad scientists 'r us). His work focuses on software engineering for AI, specifically building data-driven, explainable, and intelligent software systems. He is am an ACM, IEEE, and ASE Fellow, and co-creator of the PROMISE repository, showing that small, interpretable AI models can often outperform larger, more complex ones.

He has have published over 300 papers with 24,000+ citations (h-index=74) and advised 24 Ph.D. students. He serves as Editor-in-Chief of the Automated Software Engineering journal and, from 2010 to 2026, as an Associate Editor for IEEE TSE.

His research is supported by $19M in competitive grants from government (NASA, NSF, NSA) and industry (LexisNexis, Microsoft, Meta). Recent: $2.5M from NSF + $1M from NSA for trustworthy compact AI. For more details, see http://timm.fyi
