What will the next bull cycle be about?

I've been in crypto since 2013 and I have seen now 3 cycles at play. Each one seemed to have a theme that enabled it often with new tech or uses cases behind it.

• 2013 was about Bitcoin and access to markets where you could trade it for fiat currencies.

• 2017 was about ETH and smart contracts enabling new use cases and markets.

• 2021 was about NFTs and DeFi again enabling an entirely different aspect of it.

If there is a bull cycle in 2024 or 2025 what new tech or use cases do you think will be the focus of it? I am interested to hear a diversity of opinions on it.
