I listed the most innovative things that happened. They were product innovations that could have killed Facebook as a company, not RocksDB or React. At the same time I'm a software engineer, and I could write a database much easier than create something that grows faster than Facebook.

I use instagram and WhatsApp, no Facebook anymore (except messenger), as young people went there (and I'm following).

TikTok is a bit too much for me though, I think creating videos for it takes too much time, while for Instagram it's easy to take nice photos while I'm travelling.
