If you can't imagine why this is bad, maybe read some Kafka or watch some Black Mirror.
Lmfao. Yeah, ok, let's get my predictions from the depressing show dedicated to being relentlessly pessimistic at every single decision point.
And yeah, like I said, you sound like my hysterical middle school teacher claiming that Wikipedia will be society's downfall.
Guess what? It wasn't. People learn that tools are error prone and came up with strategies to use them while correcting for potential errors.
Like at a fundamental, technical level, components of a system can be error prone, but still be useful overall. Quantum calculations have inherent probabilities and errors in them, but they can still solve some types of calculations so much faster than normal computers that you can run the same calculation 100x on a Quantum Computer, average out the results to remove the outlying errors, and get to the right answer far faster than a classical computer.
Computer chips in satellites and the space station are constantly having random bits of memory flipped by cosmic rays, but they still work fine because their RAM is error-correcting ram, that can use similar methods to verify and check for errors.
And at a super high level, some of my friends and coworkers are more reliable than others, that doesn't mean the ones that are less reliable aren't helpful, it just means I have to take what they say with a grain of salt.
Designing for error correction is a thing, and people are perfectly capable of doing so in their personal lives.
Self hosting is doomed until this isn't the answer.
