INSIGHT

AI As A New Kind Of Competitor For Labor

  • AI systems can be copied at near-zero cost and improved faster than workers can retrain, creating a fundamentally different competitor for labor.
  • James Miller contrasts this to past machines that replaced tasks while leaving humans broadly useful, eroding the historical escape route into new jobs.
INSIGHT

Software Cost Falls Multiply Automation Opportunities

  • Dropping software production costs lets firms route more activity through automated systems, accelerating automation across reporting, compliance, customer service, and logistics.
  • Miller highlights 'vibe coding' and code‑building AI that lets nonengineers specify goals while AI writes and iterates code.
ADVICE

Prepare For Shrinking Junior Office Roles

  • Expect the first visible labor shifts in screen work: customer support, bookkeeping, routine legal drafting, basic research, slides, copywriting, and junior programming roles.
  • Prepare by noting firms will cut internships and junior hiring as they trust software over entry-level staff.
