This matches my experience because you don't chose who you work with. Skill level is uneven among the team. Less skilled co-workers will make mistakes that will have more consequences when the language is more permissive.
That's one of the reasons you want code reviews, but then you convert your skilled programmers to teachers. This is not a good trade, because the time they spend improving the skills of other programmers is partially wasted because programmers are free to come and go. AI could change this picture.
The name of the game is therefore to keep your teams small and skilled, but this is can be difficult because of typical company politics - e.g. "bus factor" considerations, shortening time-to-market is often achieved by adding more programmers.
