Hi David, I’ve been thinking about this since your initial tweet. Now you seem to have relaxed the rules a bit (not limited to first used in the 2010s) I’ll have a go. But first, I broadly agree with you: the 2010s weren’t about new technology innovation, more about consolidation and use in things like Uber, Just Eat, short-term bike/scooter rental etc. For all the great tech in your list, you cover the period when the NASDAQ crashed and flatlined, you couldn’t really expect more of the same. Also, I could quibble about some of your choices (in 1995 I had a Toshiba laptop which was just as usable as the desktops I used around then, though it didn’t use the 5.25in floppies I had been using for a decade, and the thought of ubiquitous moble phones wouldn’t have surprised me). I expect you’ll have similar quibbles about my list.

0.Which decade gets video conferencing that works? you didn’t list it so I’ll claim it on the back of FaceTime (2010).
1. Web-based office suites (Google docs, Office 365). Some were available ca. 2006, but large scale use was later
2. Cloud storage and compute, PaaS. Amazon web services started 2006.
3. OAuth, and OAuth-style “log in with Facebook/Google” 2010 onwards. SSO isn’t the point, that wouldn’t have surprised you or me in 2006, it’s the commercialization and concentration of authentication services for consumer/personal services and what that entails.
4. Widespread contactless payment, especially with phones, especially for small payments. As above for the change in who’s providing the service (has money been privatised while we weren’t looking?).
5. Knowledge graphs
6. Cambridge Analytica
7. Facial recognition. Not here, in China.
8. Video streaming / TV catchup (Netflix streaming 2007, iPlayer 2008)

Here’s hoping the 2020s are better. Phil
