I believe the point is that you can have perfect syntactic compatibility, but that means nothing when your program calls boost::asio or a Common Lisp defmethod and you want to interpret it as Haskell.
The only way this could work is if you write the whole stdlib in your AST system.
Of course, this still won't mean your lazy Haskell program works as an eager C program. Language semantics are too different, even between similar languages, you'll ALWAYS hit corner cases on anything more than a toy program. Even if you translate C# to Java. Well, maybe C to C++ will work decently, as few programs use the diverging features.
> Nobody wants to play a game that they don't even have a chance of winning even if they play optimally.
I play such games regularly. I'm just choosing place to die, then I try to stay alive as long as possible. Sometimes I even win, just because of pure luck. Then I win more often.
No, I do not mean the quoted section. They claim to play games where there is no chance of winning, then go on to claim they eventually win them often.

Finite Universe can get stuck in a "dead" state. Giving infinite time, it will definitely will do so. The only solution for this problem is to have infinite Universe. Infinite Universe will never stop.
Which extended features you need to have on the bicycle computer, for example? I'm already overwhelmed with features my bicomp has. (I use SC Dash M50, because I like it small pebble like size).
Generally what I said above: map, strava, camera mounted under the seat as a mirror(all mirrors I've seen take a lot of space on the handlebars), music player, notifications, calls and whatnot. I don't ride a bike every day(usually it's twice a week) but my rides are in the 60-80km range so having the basics in front of me would be absolutely perfect. At the moment every time I want to check a notification or pause strava or change my playlist, I have to pull over, take my phone out of my backpack, do my thing, put the phone back in and then continue riding. It's not a big deal by any means but it is annoying when you have to stop once every hour or so.
Strava - I can upload my route to Strava from phone connected by BLE.
Mirror - yeah, it will be nice to have. Currently, I use my ears for tracking cars behind me, which saved me lot of times. I had moped mirror mounted on handlebars for about month: it was good, but I broke it very fast. Also, I had tiny mirror on pole/stick?(non native speaker) manually soldered to left side of my glasses with metal frame: it worked good, but I look dumb when I wear them, and they were hard to store, so mirror was scratched and damaged in few days. I plan to make new version, using flex leg from another glasses with metal frame, so I will be able to fold mirror.
Music player - I use cheap Chinese open-ear headphones(Atlanfa, cannot find them online) with built-in player and FM radio. I use them almost every day. They are open ear, so I hear road very well, especially with reduced volume. They work for about 2h with FM radio on, which is enough for me.
Notifications - my bicomp can display notifications and call info from phone attached by BLE, and my headphones are alerting me too about notifications and allows me to respond to calls. However, I have problem on my bicomp (Dash M50) with notifications with emoj: they are truncated after first emoj. Sometimes, emoj is the first letter in the text. :-(
I ride for about 25km daily to/from work in hilly area.
Sun have lot of energy, so it can be used as energy source. If you plan to travel at % of c, you will need strong enough radiation and thermal shield anyway. And if you have such shield, why not just dive into Sun for refueling? Humans can stay at high orbit, when interstellar locomotive refuels.
Locomotive can harvest energy and matter from Sun and then use it to orbit around Sun, slowly gaining speed, until it will no longer will be able to compensate сentrifugal force. Then it can reach high orbit passively, pickup pilots on high orbit, and be ready to flight, with full tanks. Or it can dump fuel, and do another dive to Sun, for more fuel.
If it will survive Sun radiation at low orbit, then it may also survive interstellar travel at high % of C.
From that article the best case scenario is a billionth the acceleration you are looking for. And you can’t take a billion stars because then you have more mass...
Edit: the interesting part of discussing the 1g is probably less a realistic proposal and more how about how the concept of acceleration quickly runs up against our mental constructs of what acceleration and distance means. I don’t know the source, but it’s probably an enlightening to discuss what it means in the context of relativity.
Ok, it would be exciting to move the whole solar system to a nicer place in the galaxy. But how many years are we not going to use to evaluate the ethics and technical risks of the experiment? :)
