As with Protonmail it would be nice if they could focus a little bit more on their core product. Importing emails is still not possible with them. As an email provider. With an open issue about it from 2018 🤷‍♂️.

- Does protonmail focus more on product?

  I would say it is even worse. Last thing a couple of days ago was a password manager which is quite lacking in functionality. Next to the encrypted cloud drive service which does not have any sync clients and an encrypted calendar service which is lacking in features that etesync has solved years ago. The most functional would be their VPN, which seems to be fine for its price.
  
  And it is not like they would not have anything to do on their email service (next to the billing system, which cannot handle you buying the pro version of the password manager if you are already subscribed to their mail service)

Aren't the normal encryption algorithms used today quantum resistant anyways (like AES256)?

I'm all for stronger privacy and security, but this just seems like a gimmick, unless I'm missing something.

- I read somewhere its only currently hard due to the number of qbits. Once they get over a certain number (I forget what) they will be breakable

- I think so, also wasn't quantum computing a real threat for asymmetrical encryption only?
  Some info over here

  Yeah, and since symettric encryption is usually used for file encryption and stuff like that, I honestly don't see the point in this.

Somehow I feel like they are going to have a desktop application for this drive service faster than Proton will.

A good option is self hosting with Raspberry Pi and Nextcloud. Using a cloud service is using someone else's computer.

- brb cloning the quantum encryption repo on my raspberry pi

  pq encryption algorithms have embedded optimized assembly implementations than can run a way less power than included in a raspi

They just change their subscription model a little while ago. Their new plans have much higher storage limits which is really good. It wasn't really needed when it was just email, but with cloud it'll definitely be useful. I'm very excited for this and I'll migrate from my legacy plan once this comes out! I have used them for 4 years now.

- it's better than NIST who previously certified an elliptic curve with mathematical weakness to offer them and NSA a nice backdoor

I genuinely hope they get this finished sooner than later.

The transistors are embedded in cheese. Totally impenetrable to quantum stuff.

- but quantum stuff can tunnel through the cheese, despite its inability to be penetrated
