The main point of Sourdough is: don’t obsess over technology, which is alienating and takes you out of the real world. Instead, obsess over food, which brings people together.
There’s probably something intelligent to say about the intersection of the two – after all, one of the subplots is about how the main character is using a robotic arm to help her make bread, and another character is using genetic sequencing to create the perfect super-food. The technology + food equation seems to work better when the technology is supporting the food, not when it’s an end in and of itself. But also, the food will be just fine without it.
Or maybe you could enjoy a sweet story about a young woman finding her way in the world and not worry about technology and food and underlying meaning. That would work too.
