Don't argue Hotwire vs React in the abstract — they're different tools. Hotwire shines for early-stage iteration, small teams, and B2B desktop experiences where a Rails monolith is fastest to ship. Choose React when you need a reusable API for a mobile app, or when the UI is canvas-heavy and cannot be server-rendered (Miro clones, Figma, Photoshop, Notion-style editors). Hotwire can still build Jira/Twitch/Amazon/Salesforce/Facebook-desktop-style apps comfortably.
