Any sufficiently sharp tool can cut deeply in the hands of the untrained. The answer isn't to dullen our blades, it's to find better apprentices and journeyman to work with.
The answer also is to have safety features. A chainsaw has to be sharp, but also has to have a chain catcher, kickback protection, etc.
I don’t think requiring programmers to always write out the type of a variable on every declaration is such a feature, but can see arguments for requiring them in some places where compiler could infer them. Types of function arguments in function declarations are an example.
