I was contemplating what the next phase after Soylent might be, say 10 or 15 years from now. I envision an implanted device that communicates wirelessly with a body worn computing device. The surgically installed device analyses blood sugar levels along with concentrations of all detectable minerals etc, and this “telemetry” is used to dispense and apportion nutrients on a regular schedule to ensure optimum energy and vitality for the user. This “mix” is dispensed at an appropriate temperature to be easily ingested on demand. (Think digital camelback dispensing soylent customised to you needs)
When a critical dehydration or energy level is detected, a gentle alarm would remind the user to take a few sips.
For the ultimate in cyborg nutrition, a different approach could be taken- bypass the oral ingestion process and pump nutrients directly to the stomach via a surgically implanted tube. Bonus feature: no artificial taste enhancers required.
Who here would go for an option like this?
