Imagine you are playing with your remote controlled car in the park.
Take a moment and really imagine it, a nice park with some obstacles and fun stuff to do. Imagine it is a nice warm day like here in Louisiana (79 degrees, no clouds, beautiful day), even though most of you are likely freezing your buns off with snow and ice. Anyways, imagine this for a moment.
Once you have that, imagine a friend, someone you know and like, brings their remote controlled car/truck to the same area to run it with you. Now there are two vehicles, and lots of fun to be had!! Then another person shows up because they see all the fun.
Imagine they call everyone they know, even people who only have prototype cars/trucks and now there are dozens of vehicles of various programming and capability pee peeing on your parade!! There are wrecks, and signal jamming, and the people themselves are annoying and throwing trash everywhere.
Now shift your imagination from that park to a sea port with lots of vessels and companies, and shipping storage, chemical storage, oil and gas facilities, and more. Imagine instead of bits of plastic, you are controlling weigh anywhere from 10,000 tons to 200,000 tons or more and can be quite agile in the water. This doesn't even breach data concerns, but just something to think about if you are bored and wanting to look into potential future issues and how to get in front of them.
What do you see on our horizon as an issue? #criticalthinking
