The iPhone was introduced in 2007. I’d say that had some pretty large effects. Reusable rockets. The explosion of social media. Electric cars. A number of other things.
Facebook stopped growing around 2013. I think that trend is if anything dwindling. electric cars and rockets are niche- the big change there is the digitisation of work which makes cars obsolete.
Well, the question was what had changed since 2004. FB gained more than a billion users since then.
Electric cars and reusable rockets are niche now, but picking up steam quickly. Seems pretty safe to say that those were watershed moments.
Remote work might be taking off, but I haven't seen the evidence of it accelerating. Seems like most companies like it more in theory than in practice. I'd love to be wrong about that, though.
