You're close, but not at all. Dubstep has derived from DnB, but at a slower tempo, with similar breaks and intelligent automations. However, one of the classifications of dubstep is 140 BPM as opposed to the 160'ish in DnB. Similar concept to Garage and Speed Garage.. Almost one in the same, but much faster tempo.
PS- Carl Cox was most notably known as a House artist, but certainly dabbled into some Techno. The late 90s and early 00s you didn't have many genres other than House and Techno lol.
You have no idea what you're talking about in this case. Those are perfect examples of dubstep, both original tracks and remixes. You need to learn about your separate genres before making these kind of statements. None of what I posted is remotely close to real Techno.
Dubstep is a sub-genre of Electronica music, the same way Techno, DnB, Trip-hop, Trance, Hardstyle, Speed Garage and etc. are a sub-genre. If someone like Jeffro says Electronica music is Techno, they're clueless.
