It’s something that has been worrying me for some time, and it leads me to think that the value of Bitcoin will go to zero or that we will have to migrate to cold wallets and in-person exchanges within some kind of private intranet to sign the transaction.

What possible solutions do you see?

Although my post here is rather pessimistic, I'm actually optimistic that we'll get it figured out. I compare it to a stubborn person who will not go to the doctor for medical treatment, even though it's needed. Eventually, the pain will be enough to get them into the office for treatment.

I really am not technically able to answer the solution question. But, there are very smart people in bitcoin who I think will figure it out. To me, it's a case of aligned incentives...they'll realize that we all have a lot to gain and a lot to lose if bitcoin "goes to zero" and therefore it'll get remedied when we reach that point.
