IMHO the breakthrough will come with an analog computer. The current systems simulate stuff through computation using switches. It’s like real sand vs sand simulator in the browser. One spins your fans and drains your battery when showing you 1000 particles acting like sand, the other just obeys laws of physics locally per particle and can do millions of particles much more accurately and with very slight increase in temperature. Of course, analog computations are much less controllable but in this case that’s not a deal breaker.
