Everyday things would be different. You have to account for tails everywhere. Bandaids wouldn’t work with fur. Would shirts be worn, or would natural fur coats be all that is there? Food workers would have full body nets. Claw tips come out of a different area and would make some tasks that use fingertips difficult (typing)…
I have explored a great many ideas that I have not shared here. Things like, I believe the real future is entirely organic compute. All technology will be grown as much as it is made. We currently still exist in the silicon epic of the stone age.
The one aspect I feel really weak on but would love to explore is scientific speculation about evolution of humans in isolated groups and how that might be influenced by environment and current phenotype concentrations over various time frames.
How the Earth will evolve across Milankovitch cycles, and the cataclysmic events that are inevitable across geological time scales are other aspects I would love to explore.
A lot of my interests and curiosities are limited by what I can do with a LLM. I wish I could train AI with more cutting edge realistic options, but the kinds of models that are smart enough to make super compelling stories only barely run on my hardware. These are not accessible for me to train in practice.
As far as your last comment on keyboards, the future is likely going to be your own offline AI assistant doing most of your input/output for you. It will end up feeling like a part of your inner voice. I just hope that is an offline and open source model being used with lots of transparency.
