I asked ChatGPT 4.0 if Poet could possibly be a scam, and here's what it said:

There's no substantial evidence to suggest that POET Technologies is a scam. The company has made significant technological advancements in the field of photonic integrated circuits and optical interposers, with its developments being recognized in the industry. Moreover, their financial information and business activities, including partnerships and product developments, are publicly available and subject to regulatory oversight due to their listings on stock exchanges. As with any investment, it's important to conduct thorough research and consider professional advice, but based on available information, POET Technologies appears to be a legitimate company engaged in advanced technology development.
