That's fine if you are in the chip business which delivers twice as much compute power / half the size every 18 months...but this does not and cannot happen in mechanical engineering. Hence a load of pseudo innovations (metric chains, low-normal mechs, Octalink, 13 gear cassettes, dyna-sys pedals etc) which offer little or nothing in benefit.
Shimano still on 12 gears.... I think their product cycle is more like 4 years than one.
Computers haven't been able to double computing power in 18 months for over a decade now.
Something like a Core 2 Quad (4 cores at 2400 MHz), which was released in 2007, is still faster than some cheap chips sold today.
12 years before you would have had a Pentium (1) 120 Mhz, which bears no comparison.
There is still some sort of progress, but my next laptop is being purchased on the basis of lower power consumption (heat), the old one being a bit knackered, better charging methods, rather than any fundamental improvement over an 8 year old laptop.
