According to Foresight News, at the Solana Breakpoint conference, Solana co-founder Toly said that because the profit margins of Apple and Android app stores are too high, there is a lot of room to enter the mobile market.
The scariest thing about working in crypto is smart contract hacks, which can happen on the L1 infrastructure itself. This is why the Solana validator client Firedancer is in the spotlight.
We are very close to finishing this work. Once Firedancer reaches a point on mainnet where over 33% of the network is running Firedancer or both clients, I will remove the beta tag.
In response to "what you hope to see from the Solana ecosystem", Toly said that you should build strange things, but more importantly, just build without worrying about failure. This is a learning process.
