You should totally give it a try sometime if you're feeling up to it and have a multi speed bike. It's really hard the first time, but so much of the challenge is mental hurdles like feeling tired, balance when you're going slow, and shifting. The physical challenge is a lot less than you might think.
I accidentally opted into a really tough commute a few years ago (~400ft ascent which is about 122m) and it was really challenging at first but it's amazing how fast you can improve.
I also bought an ebike. They are incredible for days you aren't feeling well or need to grab extra groceries. Good luck with your conversion project! I bet you'll love it
I think there's an argument to be made that with the way it was going we may have ended up in this ballpark either way. For Biden's time in office Democrats were flying rightward on immigration, just accepting the rightwing narrative and saying "yeah but we are hard on immigration too".
Ideally Democrats would learn from this election that it was the incorrect move, then shift more progressive accordingly, and I imagine some folks voted/didn't vote based on this hope. In truth I don't think they learned that and instead will continue to adopt ever more conservative positions, chasing the Republicans to the bottom.
I also don't think it's people who care about immigrants fault that trump won, nor is it productive to dunk on various demographics for holding to their morals or for being duped by poor education and siloed media. When/if we have another election and when/if we have to fight for one, we are going to need everyone who cares to be on board.
