SI's GPT-4 integration is the future of ATC in simming. The ability to interact in natural language and have the ai controller interpret deviation requests has been a game changer for me... i love it and see the $30 a month subscription fee as helping to fund the continued development effort down this path. I fly strictly vfr in GA planes in Alaska - where i'm also a pilot in rl, and SI was super helpful in preparing me for my most recent flight review a few weeks ago. I'm 100% in on this technology, if they are utilizing machine learning like it appears they are... not only will it revolutionize ATC in simming, but it also puts some light on the inevitability of AI's role in real world ATC.
