There are a few other options - Arm Trustzone, AMD SEV, RISC-V PMP, Nitro enclaves, etc, which all come with different features. Nitro enclaves does not have remote attestation, and AMD SEV includes the hypervisor in the TCB. We chose SGX because (1) it's the most mature, (2) it has the most complete feature set, especially remote attestation, which is critical for verifying that you're actually talking to the program you expect.

Got it, is Intel’s technology unique in this regard? or do you expect there will be a number of other companies with commodified solutions over time?

Alright: Intel SGX is important because it allows someone to run a computer program for someone else without having access to any of their sensitive information. This is useful because not all people want to run the programs they use themselves, so they can let someone else do it for them without sacrificing their privacy.
