(or why is no good software available ?)

this is just an discussion about the future of programming including visions and reality based expectations

'''how does a programmer in 2050 will work?'''

I expect that a classical programmer will disappear because doing programming by humans is far to expensive

'''who will write the software needed?'''

it will be a combination of a programming robot and a human who will act as a testing/quality engineer

'''how will programming in fact look like?'''

every software starts with a need. the interface between the tester and the programming robot will be designed to accept ''needs''. ''needs'' are just restriction in form of test-cases.

every software-project is defined as a round-trip between writing test-cases and testing the application.

1. every software starts with a basic set of test-cases
2. the programming robot creates a '''runnable''' application which evaluates '''all''' test-cases without error
3. the human test the application and checks if additional ''needs'' (test-cases) are useful
4. back to step 2.

example 'tcl':

tcl is a programming languages with a set of ~12000 test-cases.

1. programming view

tcl is a tool who acts as input output machine and is ''valid'' if ''all'' test-cases evaluates without error

2. testing view

every tool which evaluates !all! test-cases without error is called a ''valid'' tcl-interpreter

 => question: what is the difference ?
 => answer:   you only need the test-cases to define the tcl interpreter 
              and 'not' the interpreter itself
