alt Hacker NewsIsn't it probably just that they don't really have money in Star Trek so there is no contract promising amazing advances in the LCARS if we just pay this person or company to revamp it? If someone has money to be made from something they will always want to convince you the new thing is what you need.
Remember that in Star Trek humans have evolved beyond the desire to work for money or personal gain, so everyone just volunteers their time, and somehow this just always works.
