Recently I came to know that x86 instruction set can be regarded as obsolete. It should have been out of order a decade ago. Instead of being helpful, it can be called as burden. The only advantage of being backward compatible, it is slowing down the development of microprocessor. I believe it is the price you have to pay for another advantage. So, what are the problems that makes it a burden? If so, what are the alternatives available for future computing?
Another thing I heard is that, the current instruction sets(x86, ARM) are not really feasible for this age. They are not good enough for web related apps, GPS and more importantly cloud computing?
We are using internet, cloud computing and everything, but why would say that it is not good enough?
Thanks in advance
