2009 "Though desktop PCs are still common for data storage, individuals primarily use portable devices for their computer-related tasks." sounds pretty realistic now.
So does 2019 "People experience 3-D virtual reality through glasses and contact lenses that beam images directly to their retinas (retinal display). Coupled with an auditory source (headphones), users can remotely communicate with other people and access the Internet." with the current progress of AR and VR (although it might be a few years late).
My point is, you've nitpicked this in a series of predictions which may or may not be true. Kurzweil's betting a lot on 2045 and AGI, and hoping that 2029 will help him reach that age. The rest is a mix of possibly true predictions that seem absurd, like the two I've pointed out.
