Found the first chapter of this on r/HFY and was entertained, saw it got posted offsite, thought I might share here. Warning for Wattpad.
Summary:
Humanity emerges from the aftermath of the technological singularity having conquered scarcity, disease, poverty, aging, death, and, or so they thought, even war. With the aid of artificial intelligence and uplifted animals they have founded a virtual Utopia among the stars where people work only for personal development, satisfaction, or selflessly for the benefit of others.
An attempt to help another space-faring species has unexpected consequences that threatens to engulf a whole region of space, and the Human Consensus is forced to intervene. When the small conflict grows into an existential threat to their entire civilization, humanity is forced for the first time to ask the question: can Utopia survive total war?
