Science on the Rise: Starting with Cell Editors

You get the cell editor at the beginning, you can perfectly control each of your cells, and edit cells arbitrarily.
Transform brain memory cells and gain the ability to remember them.
Modifying macrophages so that they can recognize and destroy HIV.
Modify proteins in cells to create biological computers.
Transform cells so that they can divide indefinitely and gain the ability to live forever.
Transforming cells, directly generating nuclear reactions in cells, converting substances into energy, each cell is equivalent to a nuclear reactor.
Let the cells divide infinitely, multiply into a planet-sized cell mass, and build a planetary fortress.
How big is the brain hole, how strong is the cell editor!
The era of human biotechnology is opened by me!
