What the filing says about AI
3 sentences in the filing name AI. The filing names AI among the technologies competitors may use to interact with patients and payors, lower entry costs from cloud computing and AI, and the risk that patients rely on AI for part of their mental health care.
- “We also expect our competitors to continue to improve their technology infrastructure, including with the use of artificial intelligence ("AI") and machine learning solutions, to interact with patients, clinicians and payors, sell their services, utilize their data and support and grow their patient base.”
- “In addition, new developments in cloud computing, AI, and machine learning have made it easier to enter our markets due to lower up-front technology costs.”
- “If patients elect to rely on AI for a portion of their mental health care, the number of patients seeking care from licensed clinicians may decline, negatively impacting our business.”
