Surfcasting 50 years from now will look pretty much the same as surfcasting today, and as it was 50 years ago. Lines, lures, rods and reels will be newer but the act of presenting a lure to a fish in the surf zone will essentially remain the same. Look at flyfishing for example they have updated all technology but the art and secrets of presenting the fly and getting a fish to hit have remained unchanged for centuries. Surfcasting is and will be similar to that.
What DZ is offering is a humorous view of what will take place in the next "Something other than surf fishing" fad. Here's what we've gone through in the last couple decades with the latest fads for guys who don't catch from the surf. Off the top of my head.
1. Distance casting. (Always been around but comes and goes)
2. Swimming to outer rockpiles (DZ's term "wanna be a boat")
3. Technophobes for the latest and greatest outerwear, tackle and lures (funny how they always end up using eels)
4. Skishing (For your family's sake, keep your will updated)
5. Cell phone gangs.
What these above things have in common are not the techniques or technology but the people who use them. They're for guys who had a passing interest and limited success in surf fishing and now are looking for more production. They'll end up doing some other type of fishing. They may even enter the water from the surf, but that won't make it surf fishing or surf casting.
PS. Love that little submarine though
