regarding its UX, nothing close exists; when it comes to converting normies, so you have someone to actually talk to, then there are no alternatives. that's a pretty shitty state of affairs for something that shoulda been solved a long time ago.
lesson learned, I guess, don't put all your eggs in one basket and have multiple fallback solutions. I've begrudingly moved to Signal and I'm cursing it out at least once per day, can't believe the navel-gazing, self-righteous cluelessness behind it; but that's the best there is at the moment. it's beyond shitty that we're having trouble achieving what we had in like 2012 by way of XMPP and friends, let alone surpassing it.
I can't speak to the doom scenarios (death trap and whathaveyous) but I can share my experience. I was faced with buying what's considered a new "decent" bike for close to $1K and went the other way - I bought a used one for $80 in sorta OK shape; no idea who made the frame but the majority of its components are of chinese origin.
the rationale was a) to see if I even want the thing - what if I ride it a couple of times and then decide it's too much bother, and b) I should learn how to maintain it and fix the usual stuff.
three years later, I've replaced close to all of the key components by myself - wheels, crank shaft, pedals, front and rear derailleurs, brakes, calipers, cables, chains, tyres, etc. I had no experience fixing anything and got all my education from youtube. some of the gear failed and was replaced, other was upgraded preventively, mostly with shimano's value line. I'm not blaming the original components for failing, there's ample wear and tear the way I ride it and I also happen to be kinda oversized for this bike, shoulda gotten an XXL frame.
my advice is, ride the bike as is and replace components as they fail, you'll learn how to fix stuff in the process and the replacements are super cheap. only then, when you're a seasoned rider start looking into better alternatives.
