So, this is the so-called "intelligent design"? I think not.

Just to play devil's advocate...

It almost certainly is intelligent design, because it's intelligent given certain constraints (the existing gene pool in a given generation, and the fact that something working is better than something theoretically better but doesn't actually exist). God iterates using an Agile process.

Hey people under 30 or so, do you even know who MacGyver is? :)

I'm actually older than 30, but we didn't have a TV in the house when MacGyver aired, I've never seen an actual episode of the show

MacGyver is referenced all the time, to the point where I imagine most people pick it up from context clues, even if they've never seen the original show

and loads of technical debt, apparently!

Meandering arteries seems rather questionable. I suspect the existing approach is safer as the shoulder and elbows can take quite a bit of abuse and internal bleeding is a very serious issue.

I would suggest the digestive system is much more of a hack. But, losing the ability to manufacture vitamin C is both unusual (Just some primates and guinea pigs?) and problematic.

That's just nature making the best it can of a historical accident. If you were designing the eye from scratch, you'd have the nerves coming out the back like in squid. Then if you wanted something that concentrates the red and green wavelengths, you could put something else in front of the light sensing cells. You'd end up exactly where you are now, except you'd not have a huge blind spot, and wouldn't have to spend…

The blind spot is not huge. It's easily compensated for, and it appears the mammalian eye has other attributes that make it work well. We just don't have enough data to understand whether mammalian eyes embedded a major problem that had to be compensated for, or if this design has attributes that make it desirable.

It's 7.5° high and 5.5° wide. If you don't consider that huge, then that's up to you. But for me, that counts as huge, especially since it's fairly near the middle of vision. That's over half the width of my hand at arms length.

Maybe, but either vertebrates or cephalopods have to have sub optimal design. My money is on the backwards retina being the kludge.

No, neither is required to have a suboptimal design. Why do you think that? Mammals are quite successful.

If you really think about it, it's probably unavoidable. You have to reward an organism when it performs necessary functions. Which is why defecation and urination are pleasurable. You could move the piping, but you'd still have to reward the action. And if there's reward sensors there, clever animals will figure out how to trigger the reward without the action. In other words, you can move the sewer but they'd proba…

You could also make the "full tank condition" painfull, without making draining it pleasurable. Shouldn't lead to addiction, and would work as well.

At risk of being quoted ... that description already matches my internal experience of the psychology of bodily waste elimination.

I certainly wouldn't characterize urination as fun in the sense of "hm, how can I make this happen more often?"
