What a take. So from your perspective, the developing world that has largely skipped wired connections for their connectivity is all doing 'toy' stuff, not real work? There are literally billions of people with Wifi/Cell but no wired connection, you're just going to write them off as never having what it takes to do SeriousBusiness (tm)?

That you're privileged enough to consider, even emotionally, the majority of the world's connections as 'toys' is something you should recognize. Way more SeriousBusiness happens on Wifi/Cell than I think you expect, and writing off that large (and growing) group is honestly ridiculous.

On the other end of the spectrum, Steve Jobs, and Elon Musk, etc, did/do so much of their work on Wifi/Cell only that it seems insane to think that they are just doing 'toy' stuff as well.

I was on a plane about 10 years ago working on a global network of barometers for weather forecasting research using phones as sensors, and the flight attendant told me rudely to 'put away my toys now'. I've been upset at this ever since, so I'm sorry if this comes off as rude too, but honestly, wtf. I'm working on real stuff, nothing to do with 'toys', as are so many people.

Belittling the Wifi/Cell revolution is a mistake IMO.
