Wasn't this the initial promise of Smalltalk, to give end users the ability to easily modify and create their own software to fit their needs for personal computing?
`As with Simula leading to OOP, this encounter finally hit me with what the destiny of personal computing really was going to be. Not a personal dynamic vehicle, as in Engelbart's metaphor opposed to the IBM "railroads", but something much more profound: a personal dynamic medium. With a vehicle one could wait until high school and give "drivers ed", but if it was a medium, it had to extend into the world of childhood.`
