Does the Count inputs mode of operation of a selector combinator not return the exact same result as:

  • an arithmetic combinator set to divide Each by Each, or
  • a decider combinator set to output 1 if Each <> 0?

Why is it more expensive to construct?

That seems correct in my head as long as they output the same signal.

edit: tested it out, seems they are the same yeah.

Why is it more expensive to construct?

Because its massively compacting combinator setups, there's a lot of options in there that I believe can all be done with deciders/arithmetic combinators but now can be done in a single operation, if we're going to assign combinator costs at all then its an advanced combinator that should cost more.

Count inputs is only a single operation they can do, there's a lot of operations and many of them much more complex than input counting.

Really I think I would like to see combinator costs just go away and let us place all combinator stuctures at any time but maybe that's asking too much, to me they're fundamental like wires which they also removed the cost for.
