Summary based on the YouTube transcript and episode description.

Marc Andreessen personally handled all Mosaic tech support in 1993, including users who mistook CD-ROM trays for cup holders.

  • At 22 in 1993, Andreessen co-created Mosaic, the first widely used web browser, opening the internet to non-academics.
  • Andreessen personally read and answered every bug report submitted through Mosaic’s support email.
  • Being tech support for the browser meant being tech support for the entire internet and all connected hardware.
  • A common user complaint: CD-ROM trays being used as cup holders, causing coffee spills when the tray retracted.
  • The anecdote illustrates how raw and unfiltered early consumer internet adoption was — Mosaic’s user base was largely non-technical.
