> Even more importantly, what happens to teamwork? If we are all a BBM now—or rather, if we all have personal armies of BBMs, permanently locked in a manic state, springloaded at all hours to generate things for us-and-only-us—how do we work together? How do cocoons communicate, interoperate? What does a team of ai solipsists look like? It sounds oxymoronic.

One example of teamwork is how the programmers and researchers worked together to build the UNIX SYSTEM (https://www.cs.dartmouth.edu/~doug/reader.pdf). It is not a product but an environment optimized for building tools and solving practical problems with tools written in C (while BBMs were busy with Lisp in Boston .;-)

C++ is a totally different story and you need an IDE for that.
