Någon gång i början på 90-talet fick jag tag på källkoden till Eliza, omskriven i Pascal. Eliza står beskriven i historieböckerna som ett av de första försöken att skapa en processor för naturligt språk, eller en chatbot som vi skulle säga idag. Den skrevs av Joseph Weizenbaum runt 1966 och bygger på en enkel princip: Eliza fungerar som en samtalsterapeut som helt sonika kastar tillbaka användarens kommentarer till denne. Säger man ”X”, frågar Eliza något i stil med ”Vad menar du med X?” och så vidare.
Att prata med Eliza är inte övertygande någon längre stund; användaren förstår snart att samtalspartnern är ett ganska simpelt program, inte en människa.
Hur som helst, jag kompilerade källkoden och lekte lite med programmet. Historielektion eller inte, jag tröttnade efter några minuter. Då undrade jag vad som skulle hända om man lät två instanser av Eliza prata med varandra. Resultatet är ganska roligt och säger kanske något om tidiga chatbotar. Kanske kan det också lugna någon som oroar sig för att superintelligenta robotar ska ta över världen.
