Every platform has a niche.

The niche of EVM is creating a connected incubation system for startups.
EVM does this quite well and it's been cloned and forked a hundred times over thus far.
Any dev that can program on ETH can program on any EVM chain.
That's pretty powerful.

Any startup that outgrows the network it's built on will just create their own EVM network.
It's not a bad system it's just a bit clunky.
