There are literally millions of programmers that cut their teeth on little 16K machines with basic in ROM. It stopped nobody from going on to OO languages. Dykstra was wrong.
I've met countless people over the years who say they started programming in basic on 16k machines, and NEVER made it to OO languages. For some, they lost interest, but others simply weren't able to make the jump from spaghetti code to structured programming, much less OO.
