    > whereas Microsoft is actively sabotaging wine

    Do you have a link to where I can read more about this? My understanding is that Microsoft saw Wine as inconsequential to their business, even offloading the Mono runtime to them [1] when they dropped support for it.

    Project mention: Any devs actually getting a leg up using AI tools? | dev.to | 2025-02-21

    As-is today, AI tools provide some productivity gains. However, they are not replacements for experienced developers. At Uno Platform we are investing in tools which make developers productive within their current environments, such as Hot Design. Also, we are keeping a close eye and thinking of these useful scenarios to apply AI to, as we don’t believe just adding a simple LLM to it will actually add value. So, stay tuned to our blogs and Dev.to account as there is more goodness coming on this topic.
