Uploading is sounding more and more appealing.

On a more serious note, if I split into copies for that sort of reason, I'd prefer to merge and re-split occasionally or share memories across copies. Then all the mes would have all the fun, instead of each me having some.

I sort of like the idea of multiple copies of me competing for timeshare, but I'd expect it to not work out very well, as some of me would sooner or later start trying to game my own evaluation metric in order to get more time than the rest of me, which over time is an unfortunate trend.

Depending on how much computing power I had, just letting some designated TVTropes/Wikipedia/YouTube personalities run at a slower rate, and merging them back in when I'm done (or rotating copies between fun and work so someone's always working) could be an option.

Maybe the confusion is this: it is rare for time to be completely wasted: Reading TVtropes has many benefits and anything creative is obviously a good thing.

This is an interesting point. As an upload, I wouldn't have many obligations to others that I couldn't do quickly and easily. That would leave me essentially doing whatever I felt like, with little or none of the urgency of current life. If I wanted to read TVTropes, I could with no consequences. If I wanted to read the literature in particle physics, I could do that with no consequences.
