@jssmith I doubt I’m a Sigma with my low creativity and average I.Q. However, I’m self-taught on computer since the mid-80s DOS, have a JD as well as having taken science courses at UCLA along with my history and political science BAs. Became a top commercial real estate appraiser for 28 years after 5 year stint as a residential property manager (hands on repairs too)/contractor for tract homes and apartments. Funny thing is that I’m mostly self-taught since school and prefer independent pursuits rather than group activities (other than choir for 51 years). I'm probably an anomaly compared to most people who are stuck in a rut both in life and work.
I can’t do anything artistic but appreciate and know art history. I can’t compose and play piano slowly yet I am quite knowledgeable on music history (especially opera and ethnic musicology). I don’t know how to create computer programs but am able to learn how to use them with minimal instruction. My learning ability accelerates with age, possibly due to earlier knowledge compounding with new subject matter.
As to bitcoin, I don’t like it. As to blockchain, yes, I can see myself using it just as I learned to switch from a slide rule to a calculator to a computer.
I will always want to listen to music on records and CDs. Streaming just doesn’t have much of the music I want or will probably never have (ethnic, out of print on esoteric music on formats of LP, 78, RR and CD). Note that streaming music is rarely accompanied with extensive recording, composer and artist notes whereas my Marston, Romophone, Biddulph, etc. CDs have sizable booklets of notes.
