Religions and denominations of the same religion won't even agree on the nature or existence of free will. Why everyone else is so concerned about the same, I don't understand. It's more philosophy than science in most discussions. If acting as if your actions had internal agency offers better chances of survival, that's a good enough fudge for nature.

I find this unnecessarily aggressive and dismissive of people's (willfully chosen) social responsibilities. Yes, "the wife" is a convenient excuse for many things, including why you can't go out drinking tonight, even though you're really just tired from work and don't want to admit it. But presumably, if you're a decent person who has chosen to marry in this day and age, you take that choice seriously and choose your risks carefully.

Even if they are accepting of you earning more, their own boss and/or Human Resources may well have a different opinion. Woe unto those whose supervisors are also underpaid.

Viable long-term survival strategies on Earth have some pretty hard limits. Even if we master famine, disease, our own worst impulses, and asteroids, there's still the expansion of the Sun. Even if we don't expand beyond our own solar system, the technological advances gained in doing so could be invaluable for maintaining our home planet.

Perfection is a particularly anthropocentric concept. Earth was clearly a local optima, but our very capacity for trashing the planet suggests it was rather shallow. We've changed the fitness landscape like so many bulldozers in a landfill. There's no way to know what lies among the slopes beyond. Maybe we really are stuck here and defending our crapsack position from asteroids is as good as it gets. That just sounds depressing, though.

I expect we won't evolve our thinking, but if we could somehow reproduce the same problems wherever we go enough times, there's an opportunity for evolution and natural selection to operate on our societies at a galactic level. We'd buy ourselves the chance to roll the dice many, many, many more times. There will be misery and suffering along the way, sure, but that's been the cost of our existence thus far.

Assuming artificial gravity generators, who needs planets?

We stay on this rock, we die on this rock. Confining ourselves to Earth isn't a survival strategy, it's giving up. Rebuttals would be appreciated, though!

To be fair, only some do. Others just assume endless reincarnation is a thing and promise escape. Whether you see that as real distinction is something else entirely.

From the moment those copies exist, I'm not them and they're not me. We do not share subjective experiences. If you think we're equivalent and expendable, you'd best murder me in secret and pretend it never happened. You know, like incinerating me inside a teleporter or someth... oh crap, we're going there.

Yeah, I have a few issues with that comic.

> The man was not a murderer.

This is one of a few logical leaps I can't accept. His past selves are already "dead". His future selves do not yet exist. If, for example, all my ancestors are dead and my offspring not yet conceived, how does my suicide harm them in any way? None will so much as feel the grief of losing me, but I'm supposed to feel guilty over "murdering" them? (Let's not follow up on what this would mean for topics such as abortion!)

If future and past selves are of such importance that we not murder them, how can present copies be valued any less? If destroying the original is not necessary, then that must surely be murder as well. It's worse, actually, because then it's not even hypothetical; "The Machine" would be intentionally and unnecessarily ending a life.

Why do I possess the subjective experience of me, not you, and not some other me separated by time or space? Barring notions of a soul, either those other instances are not real in some sense or else there's something phenomenologically special about each, which I can only attribute to being uniquely present at a particular point in space-time. If the teleported me is a clone, their existence ought to have nothing to do with me, thus I should not be murdered for their sake. However, if the teleported me instead can only exist as a function of my past-self ceasing to be, then that's little different than how I am from any moment to the next.

TL;DR: If it works like the movie version of "The Prestige" where one copy is murdered purely for convenience, I'm not stepping into that teleporter.

If everyone has similar memories to conceal, problem solved. Who's ready to sign up for Total Recall style memory implants?

> 1. It needs a fake calendar that is randomly populated with meetings.

Not enough to compete with the real deal. Has to have multiple team calendars, so it can support conflicting mandatory meetings so people can bitch at you on Google Hangouts and Slack afterward for missing the ones you didn't attend, even though you'd told everyone in advance that you couldn't make it.

If employable programmers are as rare as brilliant young mathematicians, we have a serious problem.

> Alcohol is a poison.

A meaningless blanket statement.

Methanol is a poison, far worse than ethanol, yet you've likely consumed it in small quantities from what you would think of as non-alcoholic sources. If there's no safe level alcohol consumption, you'd best stick to consuming your fruit unripened or avoiding them entirely. Again, relative toxicity is meaningless without also taking dose into account.

You could easily say the "correct" amount of oxygen is toxic, much more so than nitrogen even at sea level, and not be technically wrong. Change up the pressure and mixture and you might find the nitrogen causing more immediate (though not toxic) danger.

Yes, I want to be around those 20 year olds when I'm in my 40s. I want to be around a few 60 year olds as well. I don't want to just talk about diversity, I'd actually rather like to live it. Those who insist on living in bubbles can have it, even if it means I have to face unemployment after 40.
