Telephone communications could not be built upon, unlike the internet, and bitcoin.

Bitcoin performs the base layer function of storing and transferring value in a decentralised and secure manner perfectly, and that’s all it needs to do.

Privacy tech or faster transactions are already built on layer 2.

If theres any more technological innovations on money, it will be built upon the bitcoin stack.

If the innovation is not about money, it won’t compete with bitcoin.

Just like how any communications innovation, like Nostr, is built on top of the internet stack, instead of inventing a whole new protocol that competes with the internet.
