Income != wages
What do you mean by this?
Income inequality is still increasing.
Source? Mine is here and here although I'm happy to delve into more detailed statistical tables if you want to do that.
The ultra-rich don't get most of their obscene wealth growth from wages, they get it from investments and assets
Agreed. I was careful to phrase it as "wage earners" when I was talking about wage earners at the 90th percentile losing ground; I'm sure at the 99.9th percentile it's still going up yes, which is a problem.
the fall in average household savings shows that the increased wages at the bottom isn't translating to more financial security
Can you explain a little more what you mean by this?
it's getting eaten up by increasing prices in many different sectors.
What's your source? I sent a couple already which specifically show wages growing outpacing inflation, at the bottom end of the scale. So we have historic levels of inflation because of a couple of different reasons, and the wage growth at the bottom is still beating inflation by about 7%, which means in absolute terms it's quite a bit larger than that.
ITT: People who didn't understand the article
OP: You should not be bothered. The author's arguments are perfectly valid IMO, but they're way way beyond a beginner level. C is already a fairly challenging language to get your head around, and the author is going way beyond that into arguments about the fundamental theoretical underpinnings of C and its machine model, and the hellish complexities of modern microcode-and-silicon CPU design. You don't need to worry about it. You can progress your development through:
... and not worry about step 5 until much much later.
