Interpretation, not reported fact. Each point follows from a source listed below — follow the links and judge for yourself.

If OpenAI revokes model access to Cursor post-SpaceX acquisition, developer workflows will pivot towards native Claude Code or custom open-weight orchestration platforms. (Basis: OpenAI cutting off API/model access to Cursor following SpaceX acquisition.)
Dedicated web search indexing for autonomous agents will increasingly replace human-first search APIs as agentic traffic scales. (Basis: Keenable raising $26M seed funding specifically for an AI agent web search index.)
