Ask HN: What are the hardest problems AWS Lambda MicroVMs can solve now?

By introduction of Lambda MicroVMs, what are the most importance and challenging task we can solve with them now?

I’m looking for the answers which weren’t possible before on it.

My objective is to understand if this technology can solve really hard parts of a very common problem. Even if making it work on AWS would require a lot of work but it would be worth it.

Hence my goal is to understand what it unlocks?
