I think positive/negative is in the eye of the beholder, so-to-speak. I like the question they ask at the ER about how much pain one is in with a little chart of comparisons and one has to answer it for themselves. Don't think there is an agreed-upon meaning to pain and how much one is in/can take since we're all individual in that regard, can't really compare with anything as a standard. But then, I love going to the dentist

I would like a computer to imagine and maybe mold prototype ideas or inventions, even if only in concept drawings, from voice command. We're coming up on good voice software that allows writing to take place; why not 3D drawing?

I have trouble with doing too much fantasy daydreaming; would be nice if one could imagine a Holodeck but item by item, make storyboarding real but without the effort of programming frame by frame (have done that as a job, tedious!). The need to be more exact and work with dimensions and deal with obvious design flaws would make it harder than just wishful thinking but could allow others to see and comment on one's efforts, make it interactive with others if one wanted; could be great for working on dreams in therapy or seeing if one's idea for an invention might be worth going further on, a quick way to tell a story (to help with writing the story or inactively with a child/children) (eventually the scientists would be able to figure out how to make the images move and be added together, etc. like an animated gif with scroll; an imagined video without a literal camera) and one could imagine fears and practice dealing with them so one wouldn't worry as much (role playing; eventually the scientists would be able to make the images interact so you could make a speech with hecklers and/or envision the audience naked and have them be upset instead of you, you could laugh :-)
