I’m wondering if the Touchbar designers intentionally wanted to have Siri trigger by accident. I could imagine how the wrong incentives could have led to this. A program manager with Siri gets a bonus if a Siri activation target is met, he or she then goes to the Touchbar design team and incepts them with the idea that a Siri button needs to be placed in a certain spot making it prone to triggering.
Voila! Conspiracy theory.
I’m pretty sure this isn’t a conspiracy theory, but it does seem to be an annoying design flaw. That said, the beauty of the Touchbar is that it’s a virtual interface. It can be reconfigured. I haven’t done that yet, but it means that Apple could easily push a software update to fix it. Let’s hope they do.
