As usual, disclosure that this is a review of a free ARC.
While the blurb for Amorphous is factually accurate, it is somewhat misleading. It would imply that there is consistently more action and focus on the mold invasion than actually occurs. Similarly, the 'quirky AI' (which given the rest of the book is a little more irritating than ingratiating) comes in roughly for the last twenty percent of the book, and the journalist so specifically called out gives us relatively limited internal monologue/experiences once the action actually happens.
The book is not badly written exactly, and at least some of the characters are interesting and engaging. Unfortunately, we spend the majority (easily three quarters, if not more) of the book bouncing between these characters perspectives in a progression of 'talking head' scenes. Various groups of our main characters sitting around tables, standing around other places, being in lecture halls, with nothing but protracted dialogue that only vaguely (and eventually...after the fact...) connects to the plot and themes. Its mostly philosophical and political conversations. This continues even in high stress, dangerous situations once the promised invasion actually does start, in a fairly unbelievable and unrealistic way. Because more than anything this philosophical dialogue is the clearly the point, some of the characters do feel more like caricatures of folks embracing certain stereotypical views. There's also a certain good faith nature to how these various folk engage in these discussions that, quite frankly, one does not typically find outside of academia. And while many (one might say, too many) of our characters are essentially academics or come from academic backgrounds, there are those who are most certainly not. 
I'm also very confused by the near future world that's been constructed. In some ways it seems to have embraced strong (and one might say necessary) socialist practices, yet somehow still seems to glorify and embrace some of the worst aspects of capitalism and (at least in some areas) alt-right practices. There's really no reason it should be functioning? The characters, despite *all* of the dialogue about philosophy, seem to universally hold no real committed political feelings or leanings, one way or another.
I did particularly like the 'Kickin It' faux new segments the most, even if later the journalists both took real extreme turns in terms of personality that didn't seem accounted for via normal character development.
