Gemini can and does send everything to Google.

Apple's challenge is they want to maintain privacy, which means doing everything on-device.

Which is currently slower than the servers that others can bring to the table - because they already grab every piece of data you have.

Apple is not trying to do everything on-device, though it prefers this as much as possible. This is why it built Private Cloud Compute (PCC) and as I understand it, it’s within a PCC environment that Google’s Gemini (for Apple’s users) will be hosted as well.

This isn't planned to be exclusively on-device. Siri isn't exclusively on-device now, to begin with.

No they aren't, that is why Private Cloud Compute is a thing.
