I think DAWs at the level of Ableton live are going to be hard to replicate, and at best, they will be a toy for not serious producers... Imagine working for 80 to 120 hours into a project that has 120 tracks and then the whole thing crashes on you. Not saying this cannot happen with Live (that's why it does backups on the background). What I'm saying is that companies like Ableton earn me more trust because I know they are serious about their work and more reliable.
I mean, vibecoded apps can be fine if you are editing just an image, or a small video you are editing for nothing serious, as a beginner, etc.. but for people that is serious about making videos or making songs that take a lot of effort and time, paying 159 euros to upgrade every 3 to 4 years is a no-brainer (I already pre-ordered it).
I think the assets (the sounds) are the bigger barrier to entry.
I worked at Ableton for a bit. They were telling me about users that play 12 hour sets and absolutely must not crash or make any mistake. And it needs to never lose a feature or drop support for just about anything. They learn from every crash and make it a priority. When it does crash, you can restart and it can recover even your unsaved changes.
