Neither would I. I was simply pointing out that BASIC wasn't the next 
thing after assembly language. Even before Fortran there were a whole 
bunch of what were usually called "autocodes", one of the more popular 
ones in Britain at least being EMA (extended Mercury autocode. So it 
wasn't really a leap, more a sequence of steps.

I could promote nuclear weapons as being a quantum leap above 
rock-throwing (millions of percent more kill efficiency), but I'd be 
falsifying the picture by omitting depressing centuries of weapons 
development in doing so.

Most BASICs weren't compiled languages anyway: BASIC's primary feature 
was the introduction of interactive execution modes and immediate 
edit/run cycling. The addition of compilation to machine code is a 
relatively recent phenomenon for (only some) BASICs, unlike other 
high-level languages.
