Dave Plummer — creator of Windows Task Manager — on autism, old-school Microsoft engineering, and the future of programming with AI.

  • Plummer cold-emailed random Microsoft employees he found on Amiga shareware registration cards, landing an MS-DOS internship that launched his career.
  • Dave Cutler (now ~85, still coding daily as a Microsoft Fellow) is to Windows what Linus Torvalds is to Linux — the sole kernel architect.
  • Plummer ranks OS/360 as the most impactful OS ever, above Windows 95 (#2) and Linux (#3), citing decades of uninterrupted commercial mainframe dominance.
  • His open-source GitHub Primes project benchmarks ~100 programming languages nightly; Zig currently edges out Rust, C++, and C on prime sieve performance.
  • Slot machines decide the outcome first via RNG, then animate the reels to match — the spinning display is purely cosmetic theater.
  • Autism’s core cognitive trait (monotropism) — intense serial focus on one thing — is also why so many elite programmers are on the spectrum.
  • Plummer’s autism career advice: present a portfolio of concrete work (GitHub history, algorithms) rather than trying to sell personality in interviews.
  • On AI coding: good programmers using LLMs become dramatically more powerful; non-programmers vibe-coding alone rarely ship production-quality systems.
