Not quite, but along the right line of thinking IMO.

Speed wise we have well and truly hit the limit of what we can do with 
silicon.

The speed improvements today are not the same kind done 20 years ago. 
Today's speed improvements come from changing and making what 
instructions run cheaper.

Consumers most definitely would benefit from higher number of cores even 
if they are slower. Why? Two reasons. First of all common programs like 
web browsers tend to use a LOT of threads. Which would mean less context 
switching over all (quite expensive and slow). Second most people do not 
max out their RAM both speed and quantity wise. RAM that matches the CPU 
clock speed is very expensive when comparing against high end CPU's and 
RAM is the real bottle neck today. Most people never get close to using 
up a CPU to its maximum capacity, its sitting idle a good bit of the time.

Intel has competition, every heard of AMD and ARM? Intel has made a lot 
of changes to their strategy in the last 10-30 years e.g. being more 
energy efficient because of ARM and AMD64 (with micro ops to implement it).

I am quite surprised that Intel even created i9 actually, it just wasn't 
required. Its like as if they took their Xeon lines, removed a bunch of 
features and only based it on the higher end ones.

Remember Xeon = non-consumer (so you get e.g. reliability and 
performance along with all the new features) and i-series = cheap 
consumer products.
