Moving from SHA-1 to SHA-2 took ~20 years - and that's the "happy path", because SHA-2 is a drop-in replacement.
The post-quantum transition is more complex: keys and signatures are larger; KEM is a cryptographic primitive with a different interface; stateful signature algorithms require special treatment for state handling. It can easily take more than 20 years.
Regulators require a transition to quantum-safe algorithms. In the EU, systems labeled as "highly important" must complete the transition by 2030; so you have to do it regardless of how quantum computers evolve.
The ambiguity goes away if you write them as "все" and "всё". Diacritics, accents, umlauts and cedillas are useful; if you omit them you do a disservice to the reader.
Could you elaborate more on the "a small VPS is free"? Except Oracle's free tier offer, I am not aware of others; I'd appreciate it if you could point me in the right direction.
