Or perhaps you're saying Vitalik isn't relevant anymore? Perhaps he's only a figurehead now or something. Or perhaps I have something more to learn about how this all works. Again, sources would be great, I'm curious for what the future holds.
Getting 2400tps per shard is already a pipe-dream, but tps does not scale linearly with the number of shards. The more shards you have, the more transactions will require cross-shard communication, bringing total tps down.
Also, the video you linked has Vitalik talking about roll-ups as the main way to scale. With roll-ups, sure, we can get to 100k tps, but like I said in this case we are not talking about base-layer anymore.
Then, please-pretty-please do not put yourself in a position of spreading misinformation. Even if unintentionally. It's hard enough to fight the stigma even when armed with good information, when "critics" see unfounded claims like yours it confirms the bias against crypto even more.

No articles. Stay away from opinion pieces. Try to get actual documentation about the project. Ethhub has some good material about it (https://docs.ethhub.io/ethereum-roadmap/ethereum-2.0/eth-2.0...). Look at the "Layer-2 scaling" section to learn about roll-ups and the many other solutions.
