While reading through the book today, I came up with a question. Where's the line between a lack of good senses and a stochastic environment? The examples we've had in class of what makes an environment stochastic (e.g. car trouble with the taxi) could be monitored with an appropriately advanced sensor array. An omniscient agent (or omniscient objective observer) would consider every environment fully deterministic.
So is there a clear line between the two? I would think that something that is beyond practical (such as monitoring the surfaces of a taxi's tires to know when it will weaken enough to burst from the pressure) would be in the stochastic column, but what about not knowing that a tire is going flat, because the taxi lacks a tire pressure monitoring system (which is practical)?
