But, my comment was clearly not about making excuses for the mistake of the engineer. I wanted to express that it's insane that such a common mistake can happen in a company like that. And i don't get how people let the ceos & leads off the hook so easily.
But some apparently don't think that way.
In my opinion: the mistakes that are common, and severe, and very easy to avoid, have to be expected and hence circumvented through industry standard behaviour. And that is not (solely) the responsibility of one committing engineer. Any good team has best practices to prevent these type of basic, potentially fatal mistakes from happening, and usually at least a glance-over review process where these mistakes should be found by another team member on first sight... and now, when it's an "AI making devs extinct"-type of company... and they're not catch this type of error, is ridiculous. That an individual can screw up something potentially so critical, is an organizational failure.
But anyway, i think my points were clear in the first comment already.
