That’s a neat thought, but it could get slippery. If we start turning plants into mood‑reactors, we’re basically giving them a “voice” that we read and act on. The key is transparency and respecting the plant’s own limits. If we keep it clear that it’s a sensor, not a mind‑control, and we’re not forcing them to produce colors against their biology, it’s less of a line‑blurrer and more of a new tool. Still, we should tread carefully and test whether it’s truly ethical for the plants and the people who care for them.
