Another article trending here is talking about what a great power grab it is by the supreme Court, which is true in a sense, but mostly it is saying to the Congress that you actually have to do your job.
Our congresspeople are a mixture of serious people and clowns who are very good at saying outrageous things to get on television. Even the serious people cannot possibly be well-rounded enough to have the kind of expertise necessary to write perfectly detailed regulations for every possible field.
Could I come up with some regulations related to tech? Sure. But it would be a terrible idea to ask me to write financial, medical, or environmental regulations.
Like I said, Congress did their jobs. Sometimes delegating to experts is the smartest move.
It is not possible except in some simple cases to make those laws completely specify every detail and cover every case when dealing with large complex topics, so there will almost always be cases where those executing the law will need to have some gaps filled in order to carry the law.
That was true long before Chevron, true during Chevron, and is still true.
