Now if only we could bioengineer our own stomachs to be that powerful

    There are sure to be tradeoffs which would explain why not every animal have evolved similar stomachs. It's probably expensive energy wise to maintain that acidity. It probably also makes it hard to maintain a healthy gut flora. Also imagine the burn if you vomit up stomach acid with pH 1.0

    Human stomach acid is as low as PH 1.5

    We are descended from scavengers

    The acid we make is PH 0.8, it goes to 1.5 when mixed with the other gastric juices

    Then why is food poisoning so common?

    I presume it's because some pathogens are adapted to us, or it's because of our changed diet since the agricultural revolution 10k years ago at most, or our population density and food production and transportation system causes greater exposure to pathogens, or done mix of all those and probably more

    The modern world is pretty complex
