Echoing what the bloke in the video said, Rotor brought out their first hydraulic dérailleur in April 2016 but this is the first that I've heard of hydraulic shifting. The OP's wording seems like it's pre-empting criticism to be the rantings of a mad opponent of technology, change and progress (no offence meant, Smoking Joe). Personally, I have no need for hydraulic shifting. It doesn't do anything that my bike doesn't already do (but it costs a lot more - I gather that the 2016 version groupset still retails at over £2,000); it might do it marginally 'better' but mine does it well enough and I can go into virtually any bikeshop in the UK (even
Halfords) and get the bits to repair or replace my system.
Technology comes and goes and gets recycled. Shaft driven bikes, chains driven bikes with derailleur, internal hub or single gears, belt drives, cable rim brakes, hydraulic rim brakes, disc brakes of various types. You can even get hydraulic power transmission. Hydraulic shifting isn't for everyone (hardly anyone, it seems) but that doesn't make Luddites of those that don't want it or would rather stick with cable or electronic shifting. I would say that you don't have to be a Luddite to dislike or criticise it and that no-one would expect a Luddite to react positively to it.
