are dynamic languages really a "use at your own risk" ? or it's about changing frame of mind ?

my take is if you treat your program as a series of data flows - then use primitives such as maps | arrays - then you don't need as much typing or typing at all. a map doesn't need to take a shape or a Person | Manager - either the keys exist or they don't and almost every language has guards to ensure you can safely navigate existence of keys.

but then again my realm is mostly around - web | data systems - if I was dealing with OS level systems and needed to make sure i have i64 ints then yeah typing would be crucial.
