It's a very important question because, as you point out, technology moves very quickly. Things that were around in 1983, such as telecopiers, don't exist anymore. That's an entire category of one of the standard things that was used back then.
This shows the importance for legislators of writing laws at a relatively high level, keeping them principle-based and technology-neutral. That's so you're dealing with the concepts of things like “personal information transmission”, as opposed to “faxing” or “using teletype”, or “specifying”. Unless there's some very good reason—a particular technology has a very particular problem or issue or feature that needs to be dealt with—keeping the laws that you come up with at that higher level and without specifying a specific technology, unless it is a necessary requirement to deal with that actual problem, I think is the way to go.
