<p>Random reply: 20 days ago you asked for my ChatGPT custom instructions to be more skeptical. It is :<p>Use an encouraging tone. Adopt a skeptical, questioning approach. Call me on things which don't seem right. List possible assumptions I'm making if any.</p>

<p>You know how to add logic on the outside of a function, by putting that function into a larger one and calling the function in the middle.<p>However, how do you inject logic INTO the middle of a function?<p>Say you have a function which can iterate over any list and given a condition do a filter. How do you inject the condition logic into that filter function?<p>In the C days you would use a function pointer for this. C++ introduced templating so you could do this regardless of type. Lambdas make the whole process more ergonomic, it's just declaring a one-shot function in place with some convenient syntax.<p>In rust instead of the full blown<p>fn filter_condition(val: ValType) -> bool {
  // logic
}<p>I can declare a function in place with |val|{logic} - the lambda is just syntactic sugar to make your life easier.</p>

<p>There is a strategy called alpha beta pruning meaning you can discard a lot of move options quickly based on the results of similar branches. That and caching similar board states means 20x options does not mean 20x CPU time.</p>

<p>That's probably assuming a solar system sized to cover typical summer energy usage. You can simply over-provision solar until you have wasted capacity in summer and little to no storage requirement in winter. Then it's just a tradeoff between battery and solar costs to find the best price point.<p>Also this calculation probably assumes no baseload power imported from the grid, where means such as wind and tidal power work year-round and help offset the need for batteries.</p>

<p>Perhaps not in a 100% world, though I'll give you the point that they are useful now.<p>In a 100% renewable world we would not be extracting or refining oil. Natural gas (used by these turbines) is a byproduct of oil drilling. Were we not burning the oil, the natural gas might be too expensive alone.<p>Also, in a 100% renewable world we would (by definition) have enough generation all the time - (covered by batteries and good baseload sources) that turbine power was no longer required to cover peak loads.</p>

<p>The free market is an analyzable simplification of the real market, however I think the assumptions hold in this case.<p>If a CEO delivers a certain advantage (a profit multiplier) it's rational that a bidding war will ensue for that CEO until they are paid the entire apparent advantage of their pretense for the company. A similar effect happens for salespeople.<p>The key difference between free and real markets in this case is information and distortions of lobbying. That plus legal restrictions on the company. The CEO is incentivized to find ways around these issues to maximize their own pay.</p>

<p>They are a bridge between those with money and those with skill. Plus they can aggregate information and act as a repository of knowledge and decision maker for their teams.<p>These are valuable skills, though perhaps nowhere near as valuable as they end up being in a free market.</p>

<p>Horizon Zero Dawn (the PlayStation and later steam game where you're an archer in a world of robots)<p>There are probably a lot of open world RPGs which are all good.<p>The linked site lists a lot of patterns that any game with an RPG like unlock system or item collection system will contain, like (some) grinding and Endowed value. Personally I feel that this is only a dark pattern when it goes beyond motivation for fun and into "I can't stop playing" addictive qualities.</p>

<p>Sure, but Fortnite's UI is set up to sell to you the whole time. After every match you can see unlocks. Before every match you spend time surrounded by other players with their skins and emotes.<p>The relationship between EXP and levels in each season only really reward you if you have a battle pass - so the more you play the more the pass seems like an attractive purchase. Once you have the pass, you're then encouraged to play more than you might otherwise want to in order to max out the time-limited rewards.</p>
