> now we have multiple hundreds of dollars thunderbolt cables This is mostly an exaggeration. Apple has a $160 3m 40Gbps cable but Cable Matters has the same for $70 (and Trebleet has a 2.5m one for $50). The 25 feet 40gbps cable from Pure Fi is the only I can think of that fits the "multiple hundreds' description at $200 but then again it's an active optical cable (it's not compatible with plain USB). > the cap on the actual receptacle component is below $10 even for ones with support for higher speeds. Maybe the actual C connector they started with is below $10 but you are looking at rather expensive redriver chips inside and careful engineering to care for the signal integrity at 40gbps.
