What does tezos bring vs eth2 besides having POS before? The way I see it is another Ethereum killer with no organic community (like Tron, Eos and a bunch more)

Eth1 docking on Eth2 on the roadmap in the next 18 months. The https://beaconcha.in/ has more solo validators online right now than people aware of tezos existence.

Tezos feel like a French project like Minitel was. Ahead of it´s time, theoretically ok supported by short sided ego first French corporate (Casino project reads like multi airlines travel points from the mid 80´s)

Don't get me wrong It worth a lot in the research fundamentals. But so much could be done joining the nationless Ethereum project.
