There's no skill involved in pitching the two nearly-identical-in-BPM tracks and nudging them into rhythm.
Put any sync button DJ in front of a proper CDJ setup, give them a couple of hours to practice and they will be able to pull off a set.
Most importantly: it is the least important part of the job. Nobody in the crowd gives a shit about whether or not you're using the sync button, it makes no difference to them. They're not there to stare at you, most of the time they can't even see what you're doing.
not sure why you are being downvoted. Beat-matching is the most straightforward and least interesting part of being/experiencing a DJ. I think every DJ needs to know how to do it but IMO most of the overemphasis on beat-matching comes from cringe gatekeeping. To me, it's akin to thinking an actor remembering their lines is the focus of acting.
Mixing vinyl well is definitely an impressive skill but I (and I suspect the vast majority of people) don't care at all about how people are mixing tracks (until it's to the detriment of the music). Most people care about what makes them dance and/or feel something.
Grimes isn’t a DJ she’s a self-admitted meth user who diddles around with a lot of hardware most people can’t afford in the first place and the results appeal to a very minor market (as evidenced by being dropped by her label and no critically or market acclaimed releases in 10 years or so).
Grimes is a performance artist who dabbled in music. She’s not a musician. Imogen Heap is a musician.
