Like, this feels a lot like when the iPhone jumped out to grab the lion share of mobile. But the switching costs was much smaller (end users could just go out and buy an Android phone), and network effects much weaker (synergy with iTunes and the famous blue bubbles... and that's about it). Here it feels like a lot of the value is embedded in the business relationships OpenAI's building up, which seem _much_ more difficult to dislodge, even if others catch up from a capabilities perspective.
