I don't know if it would, necessarily. So many alternatives are chrome-based, and part of the reason google was able to accrue that share to begin with was by putting a "get chrome now" in the corner of every search you did.
Most alternatives don't have that same kind of advertising reach to displace chrome, especially not for casual users.
Wasn't that assumption part of why the i9 MacBooks a few generations back had massive heating issues?
The fans and heatsinks weren't enough to cool the i9, even though they were fine with the i7, so performance would quickly go into the floor when they started throttling.
