What do you hope it's like?

As others have said I hope for a gradual adoption of the masses coupled with steady improvement in the tools around bitcoin. I hope for increased privacy and simplicity of tools. Ideally privacy should be easier than it is today. I hope the average person has bitcoin and has self custody of it.

What do you fear its like?

I fear we will see the US and the tradfi world "sanitize it" and people only use paper bitcoin. I fear that everyone that adopts it will be KYC'd and owned by the state.

What products do you think we'll see?

I think we'll see games using bitcoin. Up and coming games that don't yet exist. Game where bitcoin makes sense. I think we will see more of what we are seeing now. Content creators using bitcoin to support their work. Peer to peer value for value.

Where are the loud voices in Bitcoin wrong?

This one is harder for me but honestly I think a big area is the idea that bitcoin will lead to an anarcho-capitalist utopia. I just don't see that. I do think we will see positive moves away from state power but that vision will probably take centuries if it every happens. I say this as someone sympathetic to that vision.

Others are that real estate is a waste of time as are stocks. I think both of these are highly pumped up by the fiat system but with a non-fiat currency they will return to their place of utility. We still need land. Rental property will continue to be a profitable endeavor as well publicly traded companies. It will just be different. Where I think they are right is that over the next 20 years bitcoin will outperform.
