One reason for us not being in a simulation is that we have irrational numbers that are seemingly infinite. Like pi. In every simulation that we are able to do, there is a limit to how precise the simulation is. For example, using pi only to 10 digits is more than accurate enough for any simulation we want to run. If we currently live in a simulation, then we could assume that the creators would do the same thing to save on computing power, but we have found many irrational numbers that never end. There is also the argument that the parameters of the simulation would be dynamic and change depending on more and more precise observation, but obviously, that’s impossible to know.
There are a few good freelance transcription gigs online. I did rev.com in high-school and it was really easy. You basically just listen to an audio clip and type out what it’s saying. More difficult clips pay more but I think I was able to get something like 12-14 an hour doing it.
