[So true, Lara. The "senior engineers look slower" point is real: in architecture, the most expensive mistakes I've seen were almost never bad code. They were good solutions built for the wrong problem. Your two-sentence test is a great way to catch that early. And you're right that the hard part is moving earlier in the process, it matters even more now that AI makes writing code so easy](https://hashnode.com/posts/the-best-engineers-i-know-rarely-start-with-code/6a3a644ddcb704f8ad665e89/comment/6a3d52708b72310fa37b3d1f)

[Thanks Lara Laurielle , glad it landed! You nailed the knot: for years it was isolation or speed, never both. The magic of MicroVMs is you stop choosing, VM-level isolation that still resumes in about a second off a snapshot.](https://hashnode.com/posts/aws-lambda-microvms-untrusted-code-isolation/6a3b541c5cfac4ef063b667d/comment/6a3d3a22df244eaa28730ab0#reply-6a3d4dbf1b4b2ebf9840c955)
