I just want to bring my contribution, because as of today there are influencers on both sides and the reality is not black or white, it's grey.
So, I have been working on a little easy chart to show where the advantages of each technology are.

2018 market is the following:
-rim and disc bikes are available from almost all manufacturers
-on a $6000 road bike there is still a penalty of 1kg for disc bikes and a comparable groupset/bike would cost an extra $500-$1000
-Customers buy the products with the best ratio quality/price/convenience : if we compare tires and tubulars, the tire is better despite a 200g penalty over the tubular, but it' a lot more convenient to train with tires, and the rolling resistance is considered as better than tubular. Will customers be ready to pay more for an heavier bike that is in reality better only x% of the time ?
Rim or Disc road bike ?

This simply isn' true, customers & markets are highly irrational.

It's really worthless to try to argue about a topic like rim brakes vs disc brakes simply because each has advantages and disadvantages based on your riding conditions so like on most things on cycling you go with what you need, based on the facts and not marketing confusion.

Rim brake bike:
+ lighter
+ less maintenance
- rim wear
- less braking power depending on conditions

Disc brake bike:
+ better braking power (if hydraulic) in all conditions
+ rims last longer (no breaking surface)
- more maintenance
- heavier
- brake pads don't last as long
- more expensive (initially and for maintenance)

Considering we are talking about people who have knowledge in cycling and have training plans etc. the choice is really easy to make since only you know what type of riding you will be doing.

To get a top racing disc brake bike will be more expensive for no apparent reason so the companies can make more money and that's where the marketing comes along.
