Who? 
I'm a bit dubious. Script writing is no longer taught in schools. Kids type from the time they can control their fingers - and that's not going to change for a looooong time. I think it may be that a (virtual) keyboard is more efficient than hand-waving.Keyboards I don't see as too much of an issue. Virtulise them, or better yet, using something similar to what Steve S showed and text recognition software which already exists and can only get better, just hand write everything and it would appear as text for you.
Typing is (IMO) terribad on tablets and phones right now anyhow, so I don't see the issue as too concerning in that sector.
I just realised from one of the articles linked that Google Glass is up and to the right? That sounds annoying, albeit I haven't tried it.
But I second the danger of people who think they can adequately multitask and... can't.
People have been predicting the death of the PC since immediately after they took off. 1992 I believe. It hasn't happened nor is it going to.So, almost two years ago I posted this predicting the death of the PC within 15 years. I'm now considering revising that figure downwards, and adding tablets and smart phones to the same dead list.
Why?

If you read what he said it's more right than wrong.Predicting the imminent demise of the personal computer has become an annual ritual in recent years -- and each year the PC has defied the prophets of doom. This year looks set for a repeat performance.
Yes, it should be amusing.I'll repeat what I've said since the moment I heard about Google Glass: If you think people act stupid, oblivious and annoying when fiddling with their phones, just wait until this becomes popular.
Personalized subtitles. Great for movie theatres in multi-lingual communities, for the opera, for the hearing-impaired.
I assume with "steps" you mean (non-motorised) scooters - only the Dutch call them "step".If this wan't the case, we'd all walk around with Bluetooth earpieces and we's actually use Segways or those little fold-up steps that were popular in the nineties.
Too early yet to go to the electric store for switches. I guess I can start by taking a hammer to an old key board.
There is a social component that might make these technologies fail.
People will not use technologies that make them look weird, uncool or overly nerdy.
