I have it setup to be run autonomously as much as possible, the company will never go out of business (nothing is 100% but I will make sure to fight to the very end) cause I plan to just bulk buy servers once I have enough users. Lifetime currently should be up to 100 years, because it is low maintenance, I don't think server cost will affect stuff, but in future I plan to charge by 10 year period, but for now it should be 100 years.
