There are advantages to getting server-grade hardware. It’s designed to run 24/7, often supports more hard drives, ram sticks, processors, etc, and often is designed to make it very quick to replace things when they break.

You can find used servers on sites like EBay for reasonable prices. They typically come from businesses selling their old hardware after an upgrade.

However, for simple home use cases, an old regular desktop PC will be just fine. Run it until it breaks!

Slack

??? Slack works just fine on Linux

Things like lectures I agree are actually better online than in person, but there’s a lot about university learning that can’t really be replicated online.

The most obvious thing being physical demonstrations and hands on projects, which I had in several physics and engineering classes.

Also I think in-person works better for discussion sections or office hours, where talking it out and writing it on a board is often easier to do in person than online (although there are tools for these things online).

Another big thing you’d miss out on by studying online is the whole social aspect of living away from your parents and with other people your age and making friends and going to parties and such.

Honestly I don’t really want a smart context-aware Siri, I just want something I can give simple, straightforward voice commands to, and get predictable, reliable results.
