I think we will be. It has stopped.
I just upgraded my "old" Dell Precision T5500 to a X99 hand-built machine with an NVMe SSD and so on and I was rather underwhelmed: It's not as fast as a 5 year jump in architecture would have been 10 years ago (if that makes sense!), not even close.
I think Moore's law is done already. Intel have slowed their speed improvements over the last several years and are getting rid of their tick-tock.
I think it's market maturity: Things are "fast enough" (yes there are always those that push the limits, like gamers) but I reckon there are more mums and dads that just want stuff to work and will hang onto it for years than those that demand the fastest every year.
In fact, something I see in forums now is that even gamers are hanging onto their "old" 2600k chips since they are still incredibly fast.
My feelings on the OS are that the OS is something I shouldn't have to deal with much... it's merely a vessel to launch my applications (Visual Studio and SQL Server mainly) so I don't need anything else as long as I can run my applications and it's secure enough (I am still on Win 8.1 with Start8).
I am willing to go out on a limb and say that many others will be the same and from personal experience, just in my own circle, they are:
Me: Upgraded my 2010 Precision to a new machine last month
Wife: Upgraded her 6 year old MAC at Christmas
Dad: Upgraded his 8 year old Win XP machine last year for a £300 Dell
Brother: Still rocking a first gen Macbook Pro
