1. Proprietary Data (Youtube, docs, gmail, cloud logs, waymo, website analytics, ads, search, the list is huge)
2. Commercial Datacenters (theyre ahead at least)
3. Chip production (Google is manufactoring proprietary chips)
4. Consumer OS (Chrome, Andriod)
5. Consumer Hardware (Pixel)
Basically google has access to data that OpenAI will never have access to, can lower costs below what OpenAI can, and is already a leader in all the places OpenAI will need massive capex to catch up.
