Feels like every damn day I'm learning about another language feature that we CAN'T use... So much legacy code everywhere.

C# is more like C-blunt at this point.

i really felt that. Reminds me of the time i was working with C# in unity.
The language itself is quite nice, but surprisingly restrictive in features.

Fee like this lack of tackling legacy code is a big reason devs have to move on.
To get jobs you need to be up to date. But keeping jobs makes you out of date at the vast majority of companies do eventually you have to move to survive
