However, in today's age I have to say that these sorts of little fun social experiment projects are just a lot harder to engage with without the back of your head going: "I wonder if this has some data collection, or voiceprint collection mechanism behind it".
I'm not saying it does. In fact my natural assumption would be that it doesn't. But I can't be sure until I check, and look into the developer and ensure for myself that it is in fact a hobby project by someone legitimately just fooling around.
The prevalence of data harvesting on the internet has basically poisoned the well with regards to these little fun experiments.
Actually.. if you were around in the 80s, then you know that this isn't new, and not really a great concept.
