consciousness includes my past experience - my memories (my life experience)
the difference between death and coma/sleep is
continuity
continuity is ensured through memory
when i wake up from my coma i have continuity: my memories add up, starting from birth to now, and every second in between, except for my 'pause' - my coma is just a break in my consciousness, but i will continue to exist and be persistent about my current experience
when i die, there is no continuity between my current life and any previous or subsequent experiences
i cannot compare a current life to any other life; my current life started from my birth and ends in my death - that's the full story, otherwise all people on earth will have proven connections between previous lives, and not just small exceptions
even if my personality and mental capacity are the same with another previous consciousness, the previous life is not mine because i don't have access to my previous history / memories - my previous 'me' is not the same as current 'me'
So if that non-existence was followed by experience due to the birth of a sentient body, then it follows that non-existence is always followed by experience due to the birth of a sentient body. This applies to "non-existence after death" too
the podcast implies my persistence between all my lives, which is incorrect because of my missing memories from previous experiences - non continuity
computer analogy: i am typing my life story from age 0 to 70, but at the end i forgot to save it to disk (didn't 'commit' it to the hard drive). death = computer gets shuts down and i have to reboot it, but my previous life story is not saved and now is lost for ever; i have to type my new story (new life) all over again, unaware of my previous life and all its details
