Do you think that blockchain engineers are incapable of developing high throughout distributed systems due to engineering incapacity or due to real limits to how fast a strongly consistent, sufficiently secured cryptographic distributed system can be? Are blockchain devs all just idiots, or have they dumbly prioritized data integrity because that doesn't matter it's about big data these days, nobody needs CAP?

Gravitational Waves: Even though both light and gravitational waves were generated by this event, and they both travel at the same speed, the gravitational waves stopped arriving 1.7 seconds before the first light was seen ( https://bigthink.com/starts-with-a-bang/light-gravitational-... )
But people don't do computation with gravitational waves.
