You can get quite far with consistent long term approach with stuff like Duolingo. The problem is, its just one or very few... vectors or dimensions in which you progress, specifically aligned with how the material is done. I have a friend, he is doing DL for French for maybe 2 years, every day. He can talk some stuff pretty well, freezes on some other situations. Passive understanding works quite well for him too. Real use of language has many dimensions, changing also ie the ways you think in that language for example. Nothing beats real use where you have to express yourself and not skip to other languages as a shortcut, no way around this.
