This seems to be a step toward eliminating our dependence on the Y chromosome in people. We may become able to limit its expression to testes cells on microchips. It carries higher risks than the alternative chromosomes on many dimensions. Shorter lives, greater tendency to violence and crime. If technology like this makes it optional in living people, then so are the risks. Substances with lower risks are routinely controlled by regulatory agencies.

It's hard to imagine war in a world without Y chromosomes in humans. Does our species still need to be warlike?

Will never happen because women love men. Many to the point they can't help themselves and will put themselves in harms way to be around them.

It also doesn't take into account how much men love being men and doing male things/male culture.

Jennifer Putin declares Megan Zelensky is a slut and no one should sit with her at lunchtime. But seriously female aggression is also a thing though not as visible when men will readily engage in violence on women's behalf.

Another thought: risk-taking is also related to curiosity and hence progress. Would a placid society even think of making sperm on microchips?

Eugenicists, Hitler, and most recently, radical transpeople and radical feminists, etc all thought something similar as well. I don't think that's the right solution.

It all boils down to the old and dusty Nurture vs. Nature debate. And also competition; without competition there's no reason to live. If you pay close attention you'll realize that competition presents itself in different ways.

Female scientist: How did this get here ? Male scientist: Wow, it grew by itself.
