Solipsism is the idea that you can only PROVE that your consciousness is the only one that exists. Its just an extreme form of idealism, which is the idea that the only things that exist are things that exist in both you and other peoples consciousness.
The things you just talked about don't disprove solipsism in the slightest. People aging could just be your brain imagining peoples appearance changing over time. Reproduction could just be your brain creating new "NPC's" in your reality. Only 2 genders exist because your brain decided there were 2 genders.
However all of this is going off the assumption that solipsists think that reality is fake, which isnt true. Once again they only believe you cant PROVE that anything else actually exists. After all, the only reality and existence you ever perceive is your own.
The thing that dpdr sufferers get wrong is they assume that nothing else exists, which is kinda ridiculous imo
This is nonsense.
If age and others do I must not exist either because the process of me aging is the same as everybody else. Solipsism does not suggest I'm not real it's the opposite it's nobody else is real.
If I cook my dinner I can smell it, see it and taste it. If I come in from work to my dinner cooked logic suggest the sausage was fried but you are saying the magic man made it it just appeared like Star Trek and the food replicator. It only becomes cooked if I stand there?
There can only be two genders because it's the same with animals. Two of the same sex do not work to reproduce. If females don't exist Must have got here another way. Yet I still went through childhood and grew up like everybody else. There is a theropy that in reincarnation the previous soul stays with you until you are older but that's nothing to do with solipsism.
Listen reality is fake if you say you can't prove it. What solipsism can't prove is yes life could be a trick or an illusion but you can't prove millions of people are not part of this virtual experience too.
I go back to solipsism again I never heard of it so my mind made it up did it? Imagining people over time well I notice my furniture getting old I notice carpets wearing down and clothes getting old. So things do get old because time does pass. What you suggest is when I open a door everything appears when I close the door nothing is behind it. For that to happen the virtual experience would have to be beyond what human computers produce today for example a PlayStation game isn't as detailed as real life.
Solipsism is as bonkers as flat earth theory. Solipsism is saying everything just appears, joe bloggs is having that conversation because I'm here, nobody else deserves to come to earth and live a life only me im the chosen one. If solipsism is real it can't also prove millions of people are plugged into computers experiencing different versions of the earth. If solipsism is real no aliens exist because only earth exists. People breathing is all a lie, yet I'm breathing so if they are not really breathing neither am I? This is where it's bonkers "I" is so alike millions of others if you are going to doubt others existence then truth is you can't exist either but if you don't exist I would not be able to ask this question.
