For the exact same reasons you chose in it the first place: experience with React to build a single codebase for different platforms.

If AI allows you to build your native apps and keep 2 different, growing code bases in parity without needing native dev experience, then use AI. But my point of the original comment is that those decisions are different at smaller companies than Shopify. There is no free lunch.
