I didn't choose Google Chat.
I still have one friend with whom I communicate by what was once known as Instant Messaging. Over the years, we have periodically been forced to change IM clients, and we mostly just go with the flow. (It was one such change that required me to get a Gmail address, which I had been resisting.)
The most recent change came when Google announced that Hangouts was being phased out in favor of Google Chat. I didn't complain too much, because they clearly had not been supporting Hangouts for a while—it would routinely crash on me several times during a half-hour conversation.
But Google Chat is creepy. (Just one in a long line of new tech creepiness.) When my friend enters a line, Chat usually pops up suggested responses for me, clearly based on what my friend has just said—possibly even on an analysis of the whole conversation. And quite accurately, I might add. Perhaps worse than the eavesdropping itself is that on the recipient's end, there is no indication that I did not type the response myself.
Here's what it looks like. I added the "(Google's suggestion)" after clicking the "You, too!" button presented to me.
My friend's version of Chat (or maybe she's still on Hangouts) does not yet have this feature, but she says it happens on her phone when texting. In the future shall we stop thinking at all and just let the AI control the conversation? Perhaps if I were having this conversation on my phone I might appreciate these shortcuts more, since I loathe what passes for typing on the phone. But here on my computer I can type nearly as fast as I can speak, so I'd rather use my own words, thank you.
