I don't get it. Why should I defend or convince you of a throwaway anonymous business plan of a company that has long-since shuttered that I found on a random quora link?
Instead let's do this exercise.
Close your eyes and imagine clearly (please imagine this very clearly) that an engineer from 2117 transported to 2017 is talking to you, and imagine clearly saying to this person "So you would like to completely replace every single (item) in (industry) with a version of your own design that you have not built but which is better in every way and which everyone will use because it's clearly better, thereby you will completely dominate this very competitive industry that has annual R&D in the tens of billions, but you just need $2M to build a prototype and get started? And we're looking at what you want to build on these couple of pages in front of us, with high-school level physics equations that somehow every single person in this whole industry has never thought of?" Imagine clearly looking at it. And imagine clearly dismissing them.
I want you to close your eyes and imagine this scenario. Imagine it very clearly. Maybe sleep on it and try to imagine it as you're going to sleep.
Even though the premise itself (about time-traveling) is absurd, I think it is very easy for you to imagine behaving exactly as I describe you behaving. It's not far-fetched at all.
