'terrain-agnostic' originates from the combination of 'terrain,' meaning 'a stretch of land, especially with regard to its physical features,' and 'agnostic,' which in this context means 'not limited to a specific type or category.'

The term 'terrain-agnostic' evolved from the need to describe technology or systems that are not restricted by geographical features.

Initially, 'agnostic' meant 'one who believes that nothing is known or can be known of the existence or nature of God,' but in modern usage, it has expanded to mean 'not limited to a specific type or category.'
