500 Python Interpreters
As we approach the final release date for Python 3.13, I’ve seen an uptick in discussion regarding 3.13’s introduction of an optional GIL.

The costs of some parts of solar farms will drop to near zero. But some obstacles remain to make this energy cheaply available everywhere. As a result, the entire energy industry will change. What are those obstacles? How will the industry change?
