Virtual and augmented environments requires a complex, high level interface for sophants to navigate and manipulate the information and objects around them. Metaphorical programming and metaphorical interfaces provide a dream-like, malleable virtual and augmented experience that the user can shape, alter, and interact with. Each user has their own personal metaphorical overlay that represents their preferred construct for interacting with virtual environments and objects.
If your character is capable of hacking, or even spends a significant part of their time in immersive online environments, it is time to think about the "desktop theme" you use to navigate the more challenging parts of the internet. Most online spaces are intentionally realistic and model physical laws to a large degree. Think about how you might play a game like ShadowRun, or the Matrix, or Sword Art Online.
The internet itself is... less structured.
It is more like a fever dream, or a hallucinogenic drug trip, or a spirit walk. Much of the internet is no longer working in concrete or even simple abstract concepts. Now the most powerful way to interact with the internet's and the people on it is through metaphor. This is true in Augmented Reality settings as much as in Virtual Reality.
Basically, anyone in a fight in a virtual space is a bit like a green lantern who can manifest almost anything they can imagine. Hal Jordan was singularly unimaginative, relying on very basic physical objects to beat his way through with sling shots and choo choo trains.
More imaginative people might use poison, shifting winds, or beams of fire. The adepts might attack with an ill wind, defend with a fractal shield, or escape through a hyperbolic space.
The very best metamancers are a bit like wizards in games like D&D. They have a host of 'spells' to make use of to achieve various effects in the virtual part of our world. They are not all powerful - but they can be hard to handle.
For example, imagine a metamancer working in a D&D framework. In a mixed reality fight - where combatants use augmented reality as well as physical reality as the battlefield - the metamancer could cast something like Cone of Silence to disrupt enemy communications. Many layers of machine intelligence under this spell metaphor interpret the intent of the spell, write code on the fly, and trigger IAR and IVR effects.
