A HW device can remain safe if it is not assembled / created by the hands of such companies as Ledger or Trezor. I am inclined to believe that sooner or later any manufacturer of hardware wallets may come under pressure from states, and even ideological companies (supporters of the ideas of the cryptocommunity) will be forced to surrender. Therefore, I believe that the safest HW wallet will be the device that you assemble with your own hands. The BTC-community needs to look in this direction and develop such an opportunity, when even an ordinary user without special technical skills can assemble such a device as a designer. Assembled the physical part, installed the firmware, connected it to electrum and use it.
Decentralized hardware wallets must also be decentralized, otherwise all this decentralization becomes meaningless. Bitcoin in your wallet should not depend on HW manufacturers anyone.
There is nothing wrong with your post except most people aren't interested in assembling their own devices. And they shouldn't have to do that to interact with cryptocurrencies. If that becomes a norm, then we can call it a day. Crypto has no future in that scenario.
Yes, I understand your point of view. For the mass user, simple and easily understandable solutions are needed, which, in general, crypto community received as a result. Any hardware wallet is able to master the average user. But as it turns out, the side effects of these devices have been dependence on manufacturers who can do whatever they want with their products, even if it allows them to neglect the interests of their customers and may jeopardize the safety of their crypto assets.
Why do you think that cryptocurrencies have no future in this scenario? Because it won't allow the crypto to go mainstream and become just a niche product that only geeks can master. It seems that this stage is already in the past.
