We finally have a legit answer why this movie exists:

After losing her mother, her father, and a friend, the director had trouble understanding how to process that amount of grief, as it's an immense amount of loss. Everyone handles grief in their own way. No matter how much of an understanding one has that death is inevitable, it still will catch anybody by surprise when it actually happens. "You know their lives are going to end and yet it was still really hard," the director said at a screenwriting panel for the International Literature Festival Berlin. "My brain has always reached into my imagination and one night, I was crying and I couldn't sleep, and my brain exploded this whole story." The director continues, "And I couldn't have my mom and dad, yet suddenly I had Neo and Trinity, arguably the two most important characters in my life".
The director describes the feeling as "immediately comforting" to have both
Neo and Trinity alive again in The Matrix Resurrections. She said, "It's super simple. You can look at it and say: 'ok, these two people die and ok, bring these two people back to life and oh, doesn't that feel good.' Yeah, it did! It's simple, and this is what art does and that's what stories do, they comfort us." There aren't many words to express the deep amount of loss experienced, but it's good to see the silver lining for the creative director and that she was able to find something to alleviate the pain.
