decreased mining (security) incentives

yeah this I'm also curious how it will turn out, but we probably won't be here to see

technology increases pose deflation (thus a bitcoin grows in purchasing power and proportion over time)

it seems that with or without bitcoin this is already the direction we are going

population increases pose purchasing power increases over time

how does that work? I think population is peaking soon

Thanks for the link, I'll reply on that other thread about that topic.
