Upon hearing Arthur's words, Benson and Disel finally nodded assuringly, having dissolved their prior worries.
Funds were not a concern, they just hoped that their jointly invented car would go global, allowing them to leave a mark in automobile history - this was their wish too in scientific research.
A genuine scientist wasn't simply a matter of contributing to humanity and the world while also allowing their name to last through the ages, ensuring they'd be remembered by all?
This was the case with Benson and Disel. They didn't care about their self-interest and funds, what they cared about was whether they could produce results and whether their research career would be left without regret.
Moreover, Arthur still held the majority of stocks in the automobile factory, so after giving up a portion of the profits, the biggest loss would naturally be his.
The interest of Arthur himself were disregarded, what then would be the worry for Benson?
