Simplicity is described as being "disentangled" or the opposite of complexity.

I personally often picture complexity as a graph of nodes and edges:

- The more edges you add, the more complex the thing it describes.

- The more rules you can deduce about the graph (for example "it is a unidirectional circle-like") such as the flow of the edges, counting etc. the less complex it is.

The imagery in the talk describes it similar: Complexity is more knotted and interwoven. Simplicity is more straight-forward, clear and composable.

Ease is described as something being "near", also in the dimension of time. Something you already know or can learn/do quickly.

The talk goes on describing how simplicity requires up-front investment and time to achieve and also how ease and simplicity sometimes overlap and when they are at odds.
