If you deal with people, sometimes what’s mathematically won’t be seen as being better overall.
Think of this question: how can you make a 3 hour train ride better?
A mathematical solution might be to spend a lot of money to make the trip a few minutes shorter.
A people solution might be to spend a fraction of that money to give people a more beautiful experience by using prettier cushions, cleaning up the graffiti, and maybe installing some charging outlets.
Think of it with respect to a restaurant. You can spend hundreds of dollars on a machine that makes your coffee a few seconds faster. Or you can have fresh flowers delivered once or twice a week.
People prefer beauty and comfort more than speed and power.
