Positives
- The concept of utilizing idle Macs for private inference presents an innovative approach to decentralized AI, potentially creating income opportunities for users in low-income regions.
- Using a Trusted Execution Environment (TEE) to ensure model integrity is a commendable step towards enhancing security and privacy in AI applications.
- The idea of pooling computing resources from multiple Macs could foster collaboration and efficiency in local AI processing, which is appealing for businesses.
Concerns
- Concerns about the actual profitability of running inference on personal Macs suggest that the business model may not be sustainable in the long term.
- The lack of accessible hardware TEE in Macs raises significant doubts about the verifiability of privacy claims, potentially undermining user trust.
- Skepticism about the accuracy of revenue estimates indicates that the projected earnings may not align with real-world usage and demand.
