I propose that what we need are thousands of "fishing bots" that are controlled remotely by VIDEO GAME PLAYERS. For decades, some people have said "video games are nothing but a waste of time", and dismiss the skills that are required to excell as unimportant... but with the right tech, such people could have the "job" of "catching fish" for public consumption while never leaving their own homes.
- individualized control of these "sharkbots" could enable us to catch fish efficiently (possibly alive) WITHOUT the huge amount of collateral damage (i.e. things killed accidently) that current fishing techniques often cause.
- add in some prizes for top performers, and I think there would be many interested potential pilots.
- yes, onsite people would still be needed to maintain the sharkbot fleet, which would probably have a central "command center" on a nearby giant ship, that would recharge the batteries and/or fuel tanks.
