Comment #47056920
There is a distribution of optimism, some people in 2023 were predicting AGI by 2025. No such thing as trajectory when it comes to mass behavior because it can turn on a dime if pe…

The ISS’s solar arrays each weigh a metric ton and generate 35 KW a piece[0], and that’s just for the power collection. They’d need incredible leaps in efficiency for an orbiting t…

This may be more a problem with how "fit" is defined and used than with natural selection theory itself. Fitness can be hard to define beyond the trivial "these organisms which sur…

Its conceivable that the universe could encode a goal somehow, after all its so vast, but that conceivability alone is not evidence for the existence of an encoded goal any more th…

What part of it don’t you agree with? That an algorithm implementation must encode the goal that it pursues? How can something pursue a goal it has no access to a definition of? If…

That's fine, all I'm saying is that if genes don't actually have intention, then the utility of modeling them as though they do must be strictly limited, if not an outright liabili…

Yeah, that's not really good enough, by the author's own admission: From wikipedia: 'In the foreword to the book's 30th-anniversary edition, Dawkins said he "can readily see that […

This relates to why you will often see multiple mushrooms of the same type blooming at the same time in a ring pattern: the edge of the ring is the periphery of the linearly, radia…

In The Selfish Gene, Dawkins emphasized that the primary unit of evolution was the individual gene, not whole genomes. The genes were replicators and the genomes were just collecti…

You're choice of samples is rather skewed towards ones sharing a relatively recent common ancestor. Octopus and Sea Squirts are also animals, and they don't have legs or torsos or,…

Of course there is bias, the bias is provided by the natural environment where the organisms coded by the genome must thrive or die. The bias is applied after the mutation occurs, …

There is no broader context wherein natural selection can be considered to be an optimization process, that is a pernicious misconception of evolutionary theory. Fortunately, peopl…

Makes sense, thanks. I guess it would only feel like a slant if the "force" causing the odd shape, the gravity of the pulsar, was removed. Then all the extended gas would fall back…

If I'm standing near (but not directly on) the pointy part of the lemon shaped planet, do I feel like I'm standing on level ground, or am I on a slant?

The background temp at Earth's orbit is due to the incidence of solar flux, which I took account of. I'm assuming the radiators are shaded from that flux by the rest of the satelli…
