That was said by Ken Olsen, CEO of DEC, in 1977- At a meeting of the World Future Society, of all places. Granted, he later said that he was referring to large computers common at that time.
My little bit of snopes'ing pulled up an interesting ass covering that Olsen made in reference to this quote, which as time goes on still sounds equally as bad:
> I did make a number of statements and still make statements that people don't understand about computers, or delight in misquoting. A long time ago when the common knowledge was that PCs would run our lives in every detail, I said that if you stole something from the refrigerator at night you didn't want to enter this into the computer so that it would . . . mess up the computer plans for coming meals.
