Looking back on 2019, one thing I'm happy to see is that #privacy concerns are becoming much more mainstream.
When I gave a talk at LP2017 just three years ago, I began by saying "this is not a tinfoil hat presentation". If I were to give that talk today, I could confidently omit that line, because 2019 has created a far more fucked up narrative than I ever could have.
(On the downside, I haven't been able to keep up with the deluge of privacy related issues over the past year.)
