The mistake this post makes is thinking that sole engineering effort is what makes startup win.

Most of the things you build will end up in the trash can anyway. But what matters is what you get while doing them, like domain knowledge, improved processes, actual customers..

If you are ok to scrap your code in order to integrate a better model then fine. Since your model is better and does not need all the software around it, it will take 10x less time to re-do what you have, leaving you more time for things that also matter, like sales.
