And who doesn't want Otaku denim made on heirloom looms ;-)
Personally, as a software craftsman, I appreciate anyone who dedicates themself to craftsmanship. Japan seems to have a great deal of very dedicated craftspeople (NHK Online videos rule!), and Gibson is definitely a word- and idea-smith, Otaku-grade.
[[And because people need things to watch nowadays, our family personally loves NHK Online's shows 'Design Talks Plus' and 'Trails to Oishii Tokyo', as well as Grand Sumo. We find them fascinating glimpses into a very different culture, one that seems to honor craftsmanship in a way we, as Americans, find beautiful.]]
As to the characters not having 'an impact on anything', that's really how it's always been, unless you're a part of the klept. The only question is, "How you developed yourself in your lifetime to fight oppression and seek to uplift the most disadvantaged?" Because, if you don't, you're just a poorer version of the callous bastards that run the power organizations that do have an effect, effects that have, for example, facilitated global heating for short-term profit at the expense of the rest of us and our heirs.
[ETA: To see the klept in action, check out the parallel HN story about Bloomberg killing reporting on CCP officials getting wealthy in office.]
It's actually a brilliant device (not created by WG) because, as he has stated, all sci-fi is really speaking about the "now" of the author who wrote it, in terms of what they believe is possible or probable, whether the author does so consciously or unconsciously.
By presenting alternate timelines where certain major political events occurred differently, Gibson is able to comment on their effects on the "fuckedness quotient" of the moment.
By far, however, his most important message involves his introducing the concept of the "jackpot", which will eventually eclipse his notoriety for having introduced the term "cyberspace" a million years ago.
The jackpot is the sum total devastation we have slow-wrought upon ourselves that leads to more extreme weather and pandemics while providing cover for political groups to form kleptocracies. The term comes from the fact that those with money are always able to profit from change, and that they tend to be rewarded for their brutal competitiveness and ability to leverage any opportunity. And the bigger, the better, therefore a jackpot for them.
What he is really saying is, "The future you are heading for is ugly and is the direct result of the policies we are making right now as entire nations full of unconcerned people."
Then, if you read his work even more deeply, you'll find that what he is really saying is that we will always fuck ourselves up when we make decisions based upon any other reason than a compassionate, thinking heart. It's just that the problems caused by global heating have been brewing since the dawn of the industrial revolution.
