I am not a futurist, and other complaints

1. I would write about how much I'm still obssessed with Goblin except that when my fascination reaches a certain stage, I want to write fic and then I run up against the giant wall that is "I am not a futurist". And I really, really need to have at least a vague concept of what I think the future in 100 years will be like. I mean, I can accept that there's a baseline of social-cultural knowledge assumptions that I can work with, if (IF!) I assume that in the meantime there hasn't been the sort of global and regional upheaval that changed people's attitudes beyond recognition. Such as being invaded by aliens or catastrophic climate change leading to prolonged dystopia, I mean. For example, if I were to meet another human from 100 years later, there would be some commonalities that I could assume. I could assume this person has parents (likely two parents) and came from a family, and if in late teens, aspires to go to university or some kind of job training. I assume they still have jobs in 100 years and that robots and technology have not taken over everything. I assume human nature is still human nature: still capable of great kindness as well as great cruelty, still selfish and generous in turns. Other than that, I'm so terrible at conceptualising what technology, the type that people use every day, will be like. I mean, at the turn of the century, did anyone anticipate smartphones?

2. I will never ever not be ticked off at people who, when I've adjusted it to a nice, sane 24 celsius, change the thermostat to a chilling 19 celsius (or below). Who sits in a 19 degree room for hours on end? My weakness is definitely excessive air-conditioning. I start shivering and my heart starts racing and my mind goes blank. After that I feel like crying in a corner and stop realising that I could actually leave the room/building.
