Yeah, oh what an advancement forward that has been.
-Increased weight (tyre + wheel)
-Decreased lateral strength of the wheel (trig 101)
-Increased COG on the bike
Anything to sell bikes to gullible riders (and yes, I've ridden both).

Only focusing on the negatives, eh
What about things like increased stability and better traction?
By the way, saying "increased center of gravity" doesn't make sense. You can move the center of gravity because it's a position. You can't increase it.

So he probably means 'higher COG', which is false too. The rider is in the same position, just a bit lower relative to the wheel axles.
By the way, how did this discussion end up in a CX topic about TJ's discs??

" The fact is that 99.9% of top riders all around the world are not using them.
Before adding 2-300gr on the wheels and maybe something around 500gr on the whole bike for nothing, they think twice"
Is nobody considering the lower rotating mass on disc wheels that do not have to be thicker to support cantilever brakes? In the end racers will choose from what their sponsors want to sell, and from this, what makes them faster.
With more and improving disc brake choices vs. decreasing number and stagnant development of cantilever brakes it is clear to which way CX will go.

Thing is those lower rotating mass rims don't exist yet, and until there is a wider adoption manufactures are unlikely to risk the money on a die or mould for a wheel that will be pretty niche.

@euan - Only the 25mm option weighs less and I imagine many people would shy away from it for CX use (although the newer rims are beefed up compared to the older 24mm and 25mm rims). The ENVE XC tubular on the other hand weighs less than all their other road rims.

it tokk 5 years to see v-brakes on pros bikes
it took 5 years to see alloy frames, carbon
it took years to see cliplesspedalks on pros bikes.
..........................
i love my disc, especially when mud, wet or snow. a little more space for fenders.
it easy to buil a sub 7 kilobike with disc

I think until discs are allowed for road, you may not see too many manufacturers switch to discs. Many customers for cross want a bike that they can dual purpose cross and road race/crit (if necessary). If a manufacturers full line up is in discs, they exclude this group - at least for now.
I can see cyclocross going mostly full discs sometime in the near future, but for now Canti's will be fine.
