Genetic / biotech stuff, driven by CRISPR. All the ones you mentioned, except nanotech maybe, are pretty locked in to create massive changes. I think the bio stuff will be the most "surprising", not least because it's harder to to write believable breathless hype about it. Not to say there won't be plenty of attempts, but I feel like the public is a little more inoculated against wild health/medical claims than "killer AI" or "$100k bitcoin", which is both a good thing and more likely to create surprise when a few of them turn out to be true.

AR a really close second, but I think people will be a little bit more ready for it given prevalence in sci-fi and experience of rapid computer & graphics progress in our lifetime. So it's easier to "expect" a world of Pokemon Go on steroids in your AR glasses than it is, say, one where a boutique offshore firm is offering to give your baby the ability to see into the infrared spectrum or something.
