Intel Confronts a Big Mobile Challenge: Native Compatibility
smaxp writes: "Intel has solved the problem of ARM-native incompatibility. But will developers bite? App developers now frequently bypass Android's Dalvik VM for some parts of their apps in favor of the faster native C language. According to Intel, two thirds of the top 2,000 apps in the Google Play Store use natively compiled C code, the same language in which Android, the Dalvik VM, and the Android libraries are mostly written.
The natively compiled apps run faster and more efficiently, but at the cost of compatibility. The compiled code is targeted to a particular processor core's instruction set. In the Android universe, this instruction set is almost always the ARM instruction set. This is a compatibility problem for Intel because its Atom mobile processors use its X86 instruction set."

This person is likely in their 20s, I am assuming early 20s. With that said, I am in my 30s, somewhat early. My first PC was an 8088 and I've deep dived into every modern processor since then. Even with the debacle that was Windows 7 and 8, I am still going to stand behind x86 as a great architecture that can stand the sands of time.
Scalability: What other architecture has scaled so far that it was completely decimated two competing architectures from the past and the future at the same time. The original 8088/86 was 3mhz, the latest x86 offering is 4ghz.
Popularity: Both Apple and Sun saw the writing on the wall, Sun saw it too late, Apple saw it early (or saw what happened to Sun). They both shifted from a proprietary processor and chipset to a more common and popular platform. Both platforms had specific benefits over x86 until x86 scaled far and beyond what they both offered.
Backwards Compatibilty: I know my x86 processor is still going start in 8-bit mode and I know that I can put it in 16bit mode and run my 1992 applications. But to that extent, x86-64 just extends the instruction set. eg ARM32 does not play on ARM64.
Let's face it. I witnessed Y2K. I witnessed every weak architecture under the sun get wiped out because it had shortcomings. Intel designed the best architecture with x86 and naysayers generally harp because it's "too big". I, for one, plan to teach my children x86 ASM so they understand the basics.. then let them find MIPS or ARM or whatever-fad-arch-is-current so they too can appreciate the design of x86.
