   Hi,   
      
   1) Classical computing = Boolean logic + von Neumann architecture   
      
   For decades, all mainstream computation was built on:   
   Boolean algebra   
   Logic gates   
   Scalar operations executed sequentially   
   Memory and compute as separate blocks   
   Even floating-point arithmetic was implemented on top of Boolean logic.   
      
   This shaped how programmers think — algorithms expressed   
   as symbolic operations, control flow, and discrete steps.   
      
   2) AI accelerators break from that model   
      
   Modern accelerators — GPUs, TPUs, NPUs, and custom matrix   
   engines — use a different computational substrate:   
      
   Instead of Boolean logic:   
   → Bulk linear algebra over vectors/tensors   
      
   Instead of instruction-by-instruction control:   
   → Dataflow graphs   
      
   Instead of sequential compute on registers:   
   → Massively parallel fused-multiply-add units   
      
   Instead of manually orchestrated loops:   
   → High-level declarative specs (XLA, MLIR, TVM)   
      
   Have Fun!   
      
   Bye
