I predict that bci technology will be good ~enough in a few years that we will see recreational hive minds offered as a new frontier of indulgence and adrenaline. Shortly after this becomes popular, people will start to hive with plants and animals at *Feedback Lounges* in search of new highs.
This will first be loosely regulated, moral panics might ensue (one person per nervous system!), and eventually it could either become a high or low class way of connecting. I could see a future in which hiving is seen as low-class because it speeds up the connection process; if you're wealthy, you can afford to take your time getting to know someone. Similarly, I can see the tech simply being too expensive and difficult to access, causing it to be a pastime relegated to the hyper-wealthy. Likely a mixture of both in different regions will occur. Regardless, those on the frontier of human experience will likely quickly become hooked.
