I'm afraid that the predictions made in this article are more or less based on a faulty second-hand magic eight ball.

Due to the abundance of companies floating on the markets, This decade will introduce a long awaited tech crash that will reset and purge those companies unable to turn a profit. It will get harder for startups to seek capital since most of FAANG and other established companies with strong portfolios will move into novel industries that will invade their market share.

The claim that automation is going to replace those in 'medicine and law' is nonsensical for this decade. The deep learning algorithms used to obtain very accurate models are still not transparent enough to be trusted by professionals to be taken seriously or to understand the decision process. These tools will get as close as being supplementary in the medical and law professions to make their jobs easier.

Some technologies required to tackle climate change such as battery, wind and solar power are already here but it is still expensive. It would take time for the costs of this to be cheap enough to be trivially affordable for all, thus allowing start-ups and companies to innovate over expired patents to address climate change which will happen in the mid-late 2020s or early 2030s.

Handheld phones will still be here in the 2030s as they would have already replaced GPSs, modems, mini-PCs and even entry-level laptops. They will just not be used often like what we see today.

President Trump’s tweets will probably be gone, too.

Highly unlikely. When we follow the loudest sock puppets on the internet, they will always be held to account and their actions and whatever they said will be preserved forever, just like in the past.
