You know you have subjective experience, self-evidently. You can match the computation run by the neural circuitry of your brain to the computation run by the neural circuitry of other humans: because since they talk about subjective experience, you can expect this to be caused by similar computation.
Similarity is subjective. There is no fundamental reason that the ethical threshold must be on the level of similarity between humans and not on level of similarity between humans and shrimps.
