The Game of Life is one of my favorite programs, but I've never tried to go deep in learning about it, and as a result I still learn fairly obvious (with hindsight) things about it. This time I realized two things:

1. I don't need to keep checking if a cell is in bounds. Just don't update a border of cells!
2. I don't need to clean up the new array at each time step! :facepalm:
