Re: Programming by Pictures - been a dream for a long, long time
And even if it worked (Ha!) we'd still have the old problem that 'testing' is not a concept that is understood by these would-be non-programmers.
Remember when we started getting serious spreadsheets? Which allowed non-coders in Accounts to apply complicated rules to sets of data? And all those lovely stories of companies losing millions because of an erroneous formula which wasn't tested properly (or at all)?
Same with this. They may be able to feed in some rules that produce output, but if the rules are wrong...
I think we can coin a new term "Garbage In, Garbage Out"
