After being burned by a book with an extremely similar premise, I gave Upgrade a chance as I remember enjoying Blake Crouch’s 2019 novel, Recursion.
To it’s credit, the first third of Upgrade kept my interest but my enthusiasm quickly waned with the formulaic second and third parts. Any emotional resonance in the book was undermined by schlocky writing and over-explanation of the protagonist’s feelings. By the time the main character described a database query he was writing to advance the plot I was ready to be done.
