Or may be we are approaching a wall that is harder to climb than usual.<p>With unlimited computing power we could render real time highly interactive super accurate simulations which takes months to render. But we can&#x27;t because we don&#x27;t have the computing power.<p>The truth is, we are hitting multiple wall at the same time. It&#x27;s harder to shrink gates any further, it&#x27;s harder to increase clock speed anymore and it&#x27;s harder to dissipate the heat generated by the cpus. All the increase we are now getting are incremental not exponential and that is why we can run a current software on a 10 year old cpu, if the software is not optimized for multicore cpus.
