Useless: three gliders turn a block into four.

Into five, it seems to me. I mean, one block returns to the same place, but that's more like "a block turns three gliders into four blocks", isn't it?

Maybe you'd be interested in knightlife's Blockic Splitters thread, if you haven't seen it already. That was the thread where the 31c/240 reaction used in the Centipede first showed up. I guess you never know what may turn out to be useful (for some sufficiently generous definition of "useful'...!)

I don't think it has a name, but I like to call it the "pretend pentadecathlon" because it looks like a pentadecathlon for a few generations.
It can make a P9 wick in the same way it gets hassled in "worker bee":

Code: Select all

x = 1, y = 6, rule = B3/S23:T0,8

[BlinkerSpawn]

Could we call it a "worker bee" or would that name imply some vestigial relationship with the queen bee/queen bee shuttle?

[Kiran]

There is already something called a Worker bee and it is well known to be extendible, the wick is mentioned in the wiki page.

What could it be used for? Universal construction using breeders?

[Kiran]

When you think of it that way, what are universal constructors useful for? Aren't all of our discoveries technically useless?

Isn't life itself useless? Even if I make some amazing advancement in science or mathematics or anything, the universe is still going to end at some point and the existence of everyone will be forgotten.

Hopefully that's still ages from now. At least let us get a freaking loafer from a soup or something, whoever controls this universe

When you think of it that way, what are universal constructors useful for? Aren't all of our discoveries technically useless?

Universal constructors can't construct everything. They can only construct everything made from a certain subset of objects, selected so that the objects in that subset are sufficient to make a universal constructor (e.g. gliders, eaters, reflectors, duplicators) With these, they can make copies of themselves. There are still many things (e.g. spaceships, oscillators, still-lifes) for which no glider syntheses are known, so there is no known way to make those from universal constructors either.

[NoLongerBreathedIn]

Universal constructors can construct anything that gliders can.

[mniemiec]

Universal constructors can construct anything that gliders can.

Theoretically, yes. However. what is interesting about them is not everything that they can construct, but what they can construct that is useful, and what they can PROVABLY construct that is useful. (While "useful" can be a sbjective criterion, it certainly includes at least all components needed to make the universal constructor itself).

While there are a few things that are provably non-constructible (e.g. GOE patterns), for most patterns, especially large ones, glider syntheses are not known, even though they probably exist, so it is not yet provable that universal constructors can construct them.
