We are developing with agents and tools with these technologies, so full immersion is a necessity. There's so much going on it is almost impossible to stay on top of it.

Regarding paying for access, for me it is about a combination of reasons. I want to support their efforts and that of others, so we have paid accounts where possible. Beyond that, it is about being up to date on the state of the art. Some of it is paid, and some is FOSS.
