Why people choose to believe in Ethereum-replacement?

[metalfans]

Whether a blockchain can succeed or not does not only depends on the TPS, right?
I saw many blockchain projects claim that they are doing next generation Ethereum because they can achieve XXX TPS... but the truth is, i can simply clone ethereum source code, and modify some code and have a better TPS. Besides, Ethereum team is also working hard to solve those problems, why people choose to believe in another team instead of in a mature team like Ethereum's?

Also Ethereum has a mature community, and I didn't see others have the same quality ones except people waiting to make some quick money out of the ICOs.

TPS is down to the architecture and both Bitcoin and ETH rely on replication and are NOT cases of Distributed Network Architecture (DNA)
which means that they simply won't scale as was known eight years ago.

Fundamentally it becomes a singleton because only one head of the chain counts, it's 2D and not 3D if that helps.

EVO and a few others say they have it cracked and this work has been peer revived (That can be fixed) so for now
I take them at their word but to truly scale on-block you have got to accept some form of centralization even if it's just a
cluster of trusted nodes which kind of works with DNS anyway, start blocking, we start leaving
