Sorta. It’s a democracy with the voting and all that at this time. Since the person holding presidency is now above the law, then as long as the current president decides that we get to continue to have a republic, then we’re a republic. The moment a US president decides that it needs to be an official act to end voting, or just stall on voting indefinitely, then we stop being a republic. Basically, we’re living on borrowed time until the “by the people” part of the US nation is taken away by whomever we voted in as president last.
President Biden has the idea that he should respect the Constitution. He’s unlikely to decide to end the republic. If he gets reelected (and the conservatives don’t just kick off a civil war trying to end the election like they failed to do back in 2020), then we buy at least a few more years. Then… we go into a cycle where if benevolent dictators keep getting elected we stay afloat. The moment a populist gets elected president who also doesn’t personally decide to not take over as dictator, the republic ends.
The hiding of the control panel is just extra pain for the fun of it. I know it’s the same tool they’ve had for many generations now so they’re hiding it because it’s ugly, but it’s the real way to get things done. Hiding it is just making everyone’s life harder, which is basically the Microsoft approach to OS design.
