I disagree! Software does not have this problem for sure. I can’t think of one piece of software that punishes you by breaking say a document or cad file or whatever. I have old CAD files that I can open on any newer version of Autocad. They are not backwardly compatible at like 3-4 year intervals. Never, though is there a forward compatibility problem. Please name one that has this problem. All Adobe products don’t break data files with new features. There was an issue with Logic Pro but that was that they had not figured out how to store data files. Now that its cloud based there is no loss of data but still you can open old files it just would loose locations of audio parts. I can open a text file thats 30 years old lol if I could find one.
