This isn't such an unexpected outcome. Junior & senior dev roles rarely prepare staff for the type of meta responsibility that's involved in managerial work, and there's almost no exposure to the majority of your manager's duties. It's typical that the only exposure a non-manager gets to their manager's role is a 20 daily minute standup, some tickets shuffling around a Jira board, and a fortnightly 30-45 minute catch up. Then when your mastery of .NET/python/K8s/whatever is sufficiently well established, the business takes that as evidence that you'll be an adequate manager of humans, and promotes you with little additional training, and you often stop doing hands-on dev work.

Meanwhile, if you're a junior staff member at a supermarket, you're doing managerial-type work daily, and throughout your time, you get exposure to low-stakes managerial responsibility. You work alongside your manager for 9-12 hours/day, and you see pretty much everything they do. Over time, you're given more and more of the meta-managerial work, and when you finally get promoted, it's because both you and the business already have evidence that you can do the managerial work. You then continue stacking shelves 9-12 hours per day, as a manager.

I think there's something the software industry could learn from the supermarket industry's approach. They have a much smoother gradient between non-manager and manager.
