I believe that tulpas expend host's attention, unless proven otherwise.
Why do you think that attention is a central part of human thinking?
Here's what I am thinking: Attention seems to be a crucial and finite resource. I could certainly become more productive if I become more attentive, and vice versa. If creating a tulpa expends my attention, it is a negative-sum game for me; if it makes me training attention as a side effect, that's good, but not better than just training attention.
Have you never had the experience that you searched for a piece of information in your mind and can't find it, then two hours later it pops into your mind?
Sure! Sometimes I try hard to remember a piece of information, but can't. Then later, when I don't try, it just pops. Interesting, but usually unhelpful.
From what I read of the field there nobody even making a business out of the topic
Shouldn't the fact that nobody ever made a business out of the topic be counted as evidence towards impossibility to make a business out of the topic? If tulpas were monetizable in any way, why wouldn't there be people monetizing them?
Now, I fantasize that maybe our minds just need some tiny little upgrade for tulpas to become a clear advantage? Can you help me imagine what would that be?
Exocortex is what you need.
There are methods to remember things better, to wake up at a specific time, to make unconscious mind work for you. The last one may be disputable technique, because there are still debates regarding work of unconscious mind. But you do not need tulpa for that.
By the way, I have some well-detailed characters from role-playing game of mine, they act much like tulpas but without visual image in surrounding environment. I just have their pictures and appearances in mind. Another difference is that the most of them do not know about m...
There have been a number of discussions here on LessWrong about "tulpas", but it's been scattered about with no central thread for the discussion. So I thought I would put this up here, along with a centralized list of reliable information sources, just so we all stay on the same page.
Tulpas are deliberately created "imaginary friends" which in many ways resemble separate, autonomous minds. Often, the creation of a tulpa is coupled with deliberately induced visual, auditory, and/or tactile hallucinations of the being.
Previous discussions here on LessWrong: 1 2 3
Questions that have been raised:
1. How do tulpas work?
2. Are tulpas safe, from a mental health perspective?
3. Are tulpas conscious? (may be a hard question)
4. More generally, is making a tulpa a good idea? What are they useful for?
Pertinent Links and Publications
(I will try to keep this updated if/when further sources are found)
(Bear in mind while perusing these resources that if you have serious qualms about creating a tulpa, it might not be a good idea to read creation guides too carefully; making a tulpa is easy to do and, at least for me, was hard to resist. Proceed at your own risk.)
