I agree that those in the list does seem like they are going to be on more in demand in the coming years. I myself has contemplated whether I should learn to code but can't decide on which language to pick. I think the take away here is that jobs are becoming scarcer and more unreliable these days that freelancing could become the norm. Many industries prefer this set up now rather than having in-house talents.
I switched to freelancing a long time ago, as well as profitable investments in cryptocurrency assets. Of course I invest primarily in the most valuable assets that are leading the market, but also consider good enough projects that are starting to develop. First of all, $CRAT can be cited as an example, which allows developing a new concept of interaction between the brand and the end consumer. this is no longer just an idea, because today this business principle is being introduced into Big Business.
