Scalability is always great, but so far only Bitcoin and Ethereum have historically reached the limits of their blockchains, while other projects have 99.9% of their capacity unused. So, the question is, if all blockchains were suddenly to become scalable, would this solve the lack of user activity? I don't think so, there are tons of other problems, and most importantly, general population is just uninterested in blockchain.
What is worse is that even tech savvy guys, scientists, economists and others who seemingly should be interested in blockchain technology are mostly not interested in it. It looks like they have no time for examining the subject even a bit, because if they would do that they would see that it's not just another financial pyramid, but rather something without which future world is hard to imagine. I think we still lack a simple yet powerful explanation of what blockchain technology is, because we would have all those guys on our side otherwise.
Speaking as someone with a computer science background, I think that computer scientists are interested in blockchain technology. The technology itself is good, and won't be going anywhere. However, again from a comp.sci background, I think that blockchain and digital currencies have been over-hyped, over-valued in the market, and in my opinion used for scams (Bitconnect as an example.) This has tarnished the technology by association, and I do notice people in the community distancing themselves from named coins such as Bitcoins, often being at pains to distance themselves from Bitcoin lest they be lumped together with things that the would rather not.
So, I don't think it's a lack of a description of what blockchain technology is that is the problem. People in comp.sci understand the technology. It's the tarnishing of the reputation that is a bigger problem. As I view it.
I'm a big fan of digital currency technology. But, when I read posts on Bitcointalk, too often they are just people predicting huge price rises 'moon' or values dropping to zero 'gloom' with no cogent argument for either type of prediction. That's really painful to see.
