I'm more of a cat person, partly because they are usually more picky, which makes the reward of being looked at, even greater.
But it's just a living being with a brain a quarter of the size of my fist.
Feeling the same thing about a few words pushed on your smartphone by a data-center located hundreds or thousands kilometers away, I just can't understand.

I find it very difficult to respect dogs because they tend to be so shallow. I don't really want a pet that's hopelessly dependent on me for validation. There's a type of person who enjoys that kind of companion ("man's best friend"), but to me it would be too much of a chore. I would dread having to take one out on walks, take them outside to leave "presents" which I then have to also clean up, etc. It's just too much work for me, and it would be neglectful to the dog for me not to. It's better for me to just not dog.
Cats actually seem to have complex emotion, and for me that makes it a lot more meaningful to take care of them. When my cats come to me for petting or cuddles it's because they actually enjoy being around me, not because the only thing in the world that matters to them is my attention. They feel a lot more like equals than dogs do.
Sometimes my cats aren't as interested in me at the moment because they miss somebody else in the family instead. They have the ability to miss other people and to want to be with that specific other person who they miss! I don't know how to explain it, but I empathize with cats and more like sympathize with dogs. To me, it's like dogs are "dumb animals" whereas cats are practically people.
I don't know, maybe that's being too harsh on dogs. I don't mean to be harsh, they just don't really feel for me at all. I don't want to get a pet just to feel above them. That just doesn't feel like a good reason and it's not something I look for.
Even abused children can be loyal to their parents because they're scared of consequences, and often desperate for love and validation back, or at the very least attention. Some of my friends are still trapped in abusive living situations and it's absolutely heartbreaking to see what bad enough parents can do to someone.
A vertex is a point. So a point being a collection of vertices doesn’t make sense. A point in the sense you mean is a collection of real numbers equal to the number of dimensions of the space it’s in.

Not necessarily. In 3D graphics, it is common to represent points with homogeneous coordinates, where points in N-dimensional space are represented by N+1 real numbers. Using 4x4 matrices [0] to describe affine transformations of 3D points is very convenient.
(Agreed with your overall point though. Just goes to show how different some fundamental perceptions/definitions can be.)
> The extra real isn’t really part of the definition of the point in space though
It actually is. It's generally assumed to be equal to one, but it need not be.
> isn’t necessary to store to apply a 4x4 matrix
...if you assume it is equal to one, yes.
However, actually representing the fourth component is both mathematically sound and occasionally useful. For example, the midpoint of two affine points, such as (1, 2, 3, 1) and (3, 6, 9, 1) is actually just their sum: (4, 8, 12, 2), which represents the same 3D point as (2, 4, 6, 1). The fourth component can also be zero, in which case you describe a point at infinity in the given direction.
But yes, if you only use homogeneous coordinates for chaining 3D transformations, storing the extra component it pointless.
All a dog needs to do is look at you and show attachment/love. Nothing more. And they get loved back.
No need to be pretty smart, funny, or whatever else we assume we need to do to be loved. Just be there and show love first.
