There are two or three companies that do what CrowdStrike does on a scale CrowdStrike supports. Not necessarily on a technical level, but on a CEO-goes-to-the-same-golf-clubs level of business support. CrowdStrike was probably the worst of the bunch, but any of them can cause the problems CrowdStrike caused.

It'll happen again, though probably on a smaller scale. Software like CrowdStrike's is a massive single point of failure but spending twice the money to have a backup suite on part of the network to maintain basic operations when the primary suite crashes is not very popular. The short hit to productivity is worth the emergency prep in terms of financial output, and the people spending weeks on end recovering systems are expendable anyway.
