In fairness, perfect and simple almost never go hand in hand in life critical applications because simple is almost entirely incapable of accounting for and mitigating impacts from the entropy of the universe.
Couple that with capitalism (the 737 max's design, oversimplified, resulted in two disasters due to a for-profit company trying to maximize profit and minimize time to market by hacking an existing platform to compete with a new and ostensibly better one) and it's a surprise we're doing well with air travel at all.
That air travel is as good as it is is a great case for techno optimism. In spite of all the garbage we get ourselves into, we manage to make it work.
