They can learn how to do physical tasks like assembling a product by trying it a billion times inside a simulation until they have mastered it.

Not the indoor simulators but the full blown driving range. 

The lender could try running a what if simulator. 

Then they need massive R&D (either in Fremont, Austin or Bangalore doesn't matter), they also need fabrication, and then they buy more GPU to simulate FSD.

I just made a first order simulation there.

Remember, we are a billion times more likely to be living in a simulation of a universe on some alien teenager's computer than living in an actual universe anyways, per the academic philosophers, (Nick Bostrom in his 2003 paper, “Are You Living in a Computer Simulation?) 

I've read in a book that Real Estate Investment in Japan is often referred to as a "Scientific Investment" because it can be managed with profitability that is close to the simulation of earnings based on prior calculations of yields.

Can you add these two factors to the simulation? 

Its like going out and spending a huge amount of money to put a golf simulator in your home and realize after a week, I really do not like golf. 

Golf simulators have come way down in price ($3-5K for a basic unit and setup) could also work in a garage, but not an interior room.
