Returning to the simpler times of Windows XP when the internet wasn’t accessible. Classic gaming sessions were safe—no viruses until the USB was connected.
You can to some degree (Even though Microsoft overlooks many options), but I wouldn't store any confidential data there. What does "evil" mean? Criminals? Authoritarian regimes? NSA (or similar spy services, particularly those who disregard your privacy)? Edit: It really hinges on your risk profile. Whether it's a tight-knit group of thieves, a big company, local police, or even government officials (intelligence bodies or repressive states).
This isn't true, look up: Air gap malware. (in Qubes OS you are in control of which VM has access to your network, and which traffic is accepted (for example for a mail VM I will only allow it to access the mailing server and nothing else), and there is by default a vault VM where you put your password manager and stuff)
I understand where Xen is applied. However, escaping virtual machines remains fairly frequent. Here are some references: the Ars Technica article about a hack exploiting edge browser fetches, the one discussing bitflipping (though it mainly targets other VMs and the host), the Xen patch update from 2016, and the older piece on a serious VM bug affecting cloud services. Even with the mention of Subgraph, if an adversary gains access to your system and has exploits ready, they can target you. Placing all your software—including potential malware—into VMs is like hiding valuables under a tree: you assume no one will check that specific spot. If someone discovered you storing sensitive data in VMs and stole it, the responsibility lies with you. Similarly, if an attacker used a vulnerability to obtain your credentials or passwords stored in VMs, they would be at fault.
It’s considered less severe than typical exploits that fully compromise the whole system. The issue has been addressed in Subgraph. What makes Qubes more challenging is that it requires both a browser exploit and a VM exploit for Xen, making it significantly harder to achieve complete control.
The safest operating systems are OpenBSD and Windows 10. Qubes OS remains problematic due to its use of a poorly maintained Linux kernel.
