I agree. It will be high end tuning and custom shops who buy this sort of tech first, and it will be ridiculously expensive, and require yearly subscription fees, to get updated information on the new models. It would be far more useful in the middle end shops, as those are the techs who would need more help. Those shops will be priced out of the tech initially. Eventually it will get cheaper and the home user will be able to get into it for a few hundred bucks (whatever that comparison will be then in todays dollar)... That is when it becomes game changing. (not specifically mechanic software, but the types of software we are discussing - that high end extremely useful software. (planes/heli, train, electronic circuit design, mechanical engineering design in real 3d space...) Yes the bottleneck will be programming. With the latest AI models, that is scaling up quickly, well written series of prompts are doing wonders to get the basics and even much of the tuning done in one off small apps and scripts already. It isnt ready to make UI that humans would really use that I have seen yet though. Yeah Chilton manuals are still a thing, as well as the competitor Haynes. Yes there is money in this, I havent yet looked into an SDK for it. The wife and I are still busy working on tuning a LLM. I should probably make that a priority. However from my understanding, a lot of the smartphone apps will work already its just in the display of it, it is altered. So apps designed to take specific advantage of this space would be where the money is. Old type smart phone app dev will probably fall off a cliff in a few years in favor of dev specifically for this.
