You're posting in bad faith.
I didn't say "modest means." I said "more modest means" -- compared to a guy who made major cash thanks to an IPO. The vast majority of people on Earth, engineers included, have means more modest than that.
Second, I never said "need."
However, there are clearly a lot of folks who would benefit from top-tier desktop power (namely, developers) and would pay for it, but can't pay $6K.
Like I said, my parents were the definition of
middle class - a teacher and a factory worker -
and I had a $4000 computer setup in 1992 going to
college (see specs in another post). That would be
$7300 inflation adjusted.
It's hard to imagine anything less relevant than this. For oh, so many reasons.
First of all, household median income in 1992 was about $30K unadjusted: https://www.multpl.com/us-median-income/table/by-year
Which was also roughly the average salary for teachers: https://www.edweek.org/ew/articles/1993/10/20/07aft.h13.html
So your family like had roughly 2X median income. But that's besides the point. Besides, maybe they had 10 kids or something.
Can the average middle class US household sustain a $6K or $7 expense? Yes, with significant effort. And this made a lot of sense in 1992, because that's what a powerful desktop system cost and the alternative was not having a powerful desktop system. So your parents made the necessary sacrifices, and since you're posting on HN 30 years later I'm going to assume it was a fruitful investment. However, asking people to pay $6K for a computer in 2019 is an entirely different proposition. You can get that level of computing power for a fraction of the price.
I'm not particularly mad about the Mac Pro, mind you. There are alternatives and nobody's forcing me to buy one. I do, however, think that -- to return to the topic of this discussion -- that claiming Apple's "listening" to developers w.r.t. hardware is pretty laughable. Most developers want a fast-as-fuck CPU in a box, and many are perfectly willing to pay an "Apple tax", but not thousands of dollars worth.
