@Bruno021 Regarding the file formats. I see the problem mostly in the fact that over time file formats evolve away from the original standards. Especially some companies use their own "dialects". This makes it incredible hard for othere that need to read those files. What is specific "slang" and what is not? DXF is a good example. Originally limited to 32000 vertices and no subparts in it, now some companies use it totally different. Or tif. A very standartised image format. Suddenly there were layers in tifs - and transparency. Has nothing to do with the original definition. Again, hard to decide what is slang and what is in common use. Oh, another example that we users have to deal with every day - nothing to do with file formats. OpenGL. A clear definition of a standard originally. The idea was to have something that is platform independant and functioning on each computer with the frivers installed. What do we have now? Each producer of graphic cards creates their own slang to "optimise" their cards or to make specific games faster. The result? Confusion. Endless discussions what is working and what not. What driver version is functioning and what not etc etc. And more sellings too of course.
