First generation languages (1GL) were closely tied to the hardware, requiring the human operator to physically manipulate toggle switches to enter in the machine language instructions directly.
Second generation languages (2GL) can be loosely categorized as assembly languages.
Third generation languages (3GL) abstracted assembly language into a more human readable syntax.
Fourth generation languages (4GL) are distinguished from 3GH in that they are typically further abstracted from the underlying hardware.
Fifth generation languages (5GL), which abstracts the language itself such that it is based on “”solving problems using constraints given to the program, rather than using an algorithm written by a programmer.”
What will a 6GL look like?
In my opinion, it will look a lot like FlowSharpCode in which programs are written by piecing together the building blocks of smaller pieces of code (“behaviors”) using very visual tools, either a 2D canvas or a 3D virtual surface.
And while we’re at it, a 7GL?
Some may argue that a 6GL will be an AI, but again in my opinion, an AI that truly succeeds at “writing” an original program will do so by building from smaller behaviors. Expecting an AI to produce “code” in the languages that exist today is, well, a cute but absurd thought. A successful AI most likely will utilize some kind of “visualization” (whatever that looks like to an AI) for manifesting its “imagination” into concrete behaviors. And most likely, whatever visualization system the AI uses will most likely be able to be mapped onto a 3D or 4D (including time dimension) surface for us to peruse.
