I don’t feel like it’s horrible. If one of your founding members is focused on getting rich quick while the rest are trying to invest in the company long-term, then his departure very well could have helped the company ultimately succeed.
Is it horrible to suppose that someone might not be well-suited to the task of driving a business from nothing to a national concern? Because I personally suspect that of most people, including myself, and don't think of myself as particularly mean-spirited.
Also, the offspring of the man in question identifies an aspect of his temperament that led to things turning out the way they did.
Worked for a company that Citrix acquired a few years ago. They seemed to have went all in on something called Kepner-Tregoe. I left shortly after my week long training course, which I didn't get much out of other than a stay in a nice hotel. As I was leaving they were downsizing and one of their techniques was to match 2 people together and say "We will be comparing your performance against each other for the next 6 weeks, after that, the worst performer will be fired". Pretty awful.
I had a Ship of Theseus moment after getting my laptop repaired by Apple. They pretty much had to replace everything except for the bottom case, so when I went to sign in with my apple id I got a message saying "we have sent a message to your other device". But there was no other device. Took over a month to resolve and I also kept getting the annoying pop up message asking me to check the ID.
Been a while since I read both books, but other than a vaguely similar shape, what makes the Affront clearly a juvenile version of the dwellers? I read the wiki you mentioned and there is a story suggesting an early version of contact rescued them from dweller hunts, but no mention of where this idea came from. I'm a huge fan and believe I have read everything Banks has written and do not recall the story.
This is probably right and very saddening. Oh well, I guess we can still assume that Against a Dark Background is set in the Culture universe, just very far away.
