So what if you need a good idea, too? You still cannot get away with a good idea that is poorly implemented by engineers and scientists - it will also go exactly nowhere if there's any competition at all. Which there will be, unless you live in the US and can just patent the entire industry sector, that is. But we already knew that in the US, lawyers win.
Everywhere else where you don't work with a given monopoly, the mere fact of realizing non-trivial software is well over the head of badly trained programmers, and you will either never complete the software/product, or have a cripped product with drastically reduced specifications that comes at fourteen times over budget and ten times too late, is buggy, and will require massive efforts to adapt once you need it to work on a different computer / with some added functionality. Your potential customers will run for the competition or omit the use of any thing like this entirely, and that's the end of the story.
And ultimately, between having a good idea that is (in some way) feasible, and implementing it sufficiently well, the problem lies far more with the latter. That's the reason why -for instance- we don't have robots do all the manual labour for us yet, even in industry sectors where superficially similar production processes are already done by robots. We all already know that would be really nice and magnitudes of orders more efficient than any manual labour, but getting there is a slow and requires skilled workers that are not plentiful either on the software or on the hardware side of these engineering projects.
