Episode Details

Why do we still use a keyboard layout designed to prevent typewriter jams that haven't existed for a century? This week, we explore lock-in effects—the phenomenon where solutions persist long after their original problems vanish, trapping entire industries and technologies through the sheer cost of switching. From QWERTY to railroad gauges to programming languages, discover how historical accidents become permanent features of our world, and why the economics of change often defeat the logic of progress. 00:00 - Why Your Keyboard Layout Exists 03:45 - The Typewriter Jam That Changed Everything 07:20 - When the Problem Disappeared (But the Solution Stayed) 10:15 - Defining Lock-In: Paul David & W. Brian Arthur 13:30 - The Economics of Being Stuck --- Sources & further reading: • Paul David — "Clio and the Economics of QWERTY," American Economic Review 75(2), 1985: https://econ.ucsb.edu/~tedb/Courses/Ec100C/DavidQwerty.pdf • W.
