Dedicated hardware wallets help to some extent, and they already exist and work (e.x. Trezor). It's hard for people to understand backups, security updates, "don't open that funny-cat-photos.exe file from your aunt", but easy to understand "if this device is lost or stolen, my money is gone" You have to trust the hardware (open source hardware/firmware will be an improvement), and verify addresses out of band (see https://medium.com/@octskyward/why-you-think-the-pki-sucks-b64cf5912aa7 https://medium.com/@octskyward/why-you-think-the-pki-sucks-b... for solutions), but otherwise you can safely use it on even a malware infested computer. As a bonus, it can be protected by a pin (with firmware-enforced rate limits). And backups of the seed can be made in case the hardware wallet is stolen/lost/destroyed. They can even be split up using Shamir's Secret Sharing. (Eventually mobile devices will be able to accomplish the same thing. You could imagine a more advanced version of Apple's "Secure Enclave" that presents the user with a UI (rendered by the Secure Enclave coprocessor) to authorize transactions)
