<p>I want to see that shader. How is sloshing implemented? Is the volume of the bottle computed on every frame?<p>Clearly, there's some sort of a physics simulation going on there, preserving the volume, some momentum, and taking gravity into account. That the result is being rendered over the shader pipeline rather than the triangle one doesn't make it any more or less "real" than the rest of the game. It's a lie only if the entire game is a lie.</p>

<p>"Reasonable" is an unfortunate word IMO. An assumption doesn't come out of reasoning. We can't even estimate the probability of this assumption being right because we can't see the future.<p>The best way this word fits is that we can reason towards the conclusion that whether laws will change or not is an assumption.</p>

<p>If you're clipped in, why would you keep feet from sliding?<p>Preventing sliding by pushing is how effort is wasted and is a possible explanation why a cyclist might feel much stronger when clipped in and no longer has to push - while attributing the lower effort to the upstroke pull.</p>

<p>Those are not necessarily examples of <i>lifting</i>. Those could as well be explained by the contribution of <i>not pressing</i> on the opposite pedal (to keep the foot from sliding).<p>And not pressing doesn't shine any light on the force of lifting.</p>

<p>While I agree that your child is not you and FOSS doesn't need to be your child's value, it needs to be said that<p>FOSS is the software author's value. It correlates with the author's intentions, their incentive and the software's shape and influence on the user – your child. It's a way to delineate content you want your child to see and that which you don't (and thus we circle back to the idea that you imposing a policy ultimately means imposing your values anyway).</p>
