I think the drone approval/disapproval is rooted in 1 thing - vision vs present.
If you watch it, and appreciate it as the first widespread demonstration of a technology that has an infinite growth potential - it was awe inspiring and amazing.
If you watch it, expecting to see a final product that is a giant flying HD billboard that makes you question reality - it was mediocre at best.
Again, this was 300 drones with basic 2D representation. If you read the articles, press releases, and watch the Intel engineering team who is responsible for this discuss it - you realize this is their Proof of Concept. Their real vision is drones that are 1/2 to 1/4 the size, twice the battery, twice as bright, and 1000s of them. They are likely 3-5 years away from the first engineering proofs of those drones. Very close, but not imminent.
So yes - the show was "lackluster" from a blew my mind perspective. It was amazing from the fact it was the first time ever done on a stage this large and for what the future holds. V1 of the drones. Usually V3 of a new technology/product is the deal breaker.
