It would be cool if the 1st layer would be better investigated as SMTs will open such a high range of possibilities.
You are right, 3-4 years make a lot of difference in the industry as it develops, from a blockchain point of view, I see Hive still one of the best, regarding cost and speed and the possibilities it offers, so hope that in 3-4 years it shall reach again top10 at least from value rank.
