The top tech trend of 2020-2030 is going to be video. Currently the most popular apps are based on Video. I believe that companies which already have infrastructure and skills in video technology will succeed in the future.
YouTube will shatter
Currently YouTube is the undisputed king of all online video platforms, but i believe that might change. YouTube only supports a single type of video content (+10 Minute, Family friendly, non controversial, advertiser friendly content) Video can be used for so much more than this. In the future i believe that there will be more specialized services which will siphon users away from YouTube. A great example is Tiktok, it's currently the best place to share short form video content. I believe that similar specialized video services will taking users away from YouTube.
MindGeek might challenge YouTube
MindGeek is a massive tech company with focus on video sharing services. Currently they focus on XXX videos but they certainly have the infrastructure to create a family friendly video platform. According to some rumors they are already building a challenger for YouTube. Consumers would definitely benefit if YouTube got some serious competition.
Copyright laws might change video
I remember when big data and tech company data collection became a big topic of discussion. EU politicians scrambled and started making laws regulating data collection. This affected Facebook and Google tremendously, because they had to start complying with the new data collection laws. Something similar might happen with the copyright laws. New copyright laws might change every video platform. Here is a good video on the current copyright laws. YouTube has a very shaky copyright policy because the actual copyright laws are outdated. Once we experience an overhaul of copyright laws it might either hurt or help video sharing platforms.
Here is a great video discussing the potential of video apps. I will continue developing new apps based on video sharing and hopefully one of them will become successful.
