Thinking about technology on my run today. The bicycle came to mind as the technology (non-medical) with the greatest upside and least downside. The bicycle is very efficient for local transportation, but far from the most efficient means to do any particular harm.

I was once run all the way down by a drunk cyclist, and got up with minor scuffs.

I'm trying to think of other technologies that are both useful and very hard to use directly for evil.

@mulegirl The pen.
@iamdavidobrien Oh yeah! That's one I for sure take for granted.

@mulegirl

Would you count:

Books or the lightbulb

@dkiesow there are some very evil books out there. Lightbulb maybe! Gas lighting was for sure bad. So it was an improvement over that, and it can be power source agnostic.

The bummer is how commercial lightbulbs were engineered to be less long-lasting on purpose.

@mulegirl gloves are one of my favourite pieces of technology: enhances existing capabilities (hands) and introduces them to new environments (toxic, wet, sharp, ultra warm)

@cblgh Oh gloves is good!

As long as you don't use them to start duels.

@mulegirl How about the compass? Its primary function is harm-avoidance for its user, but provides no way for the user to inflict harm on others.

But then again there are many harms human civilisations might not have been able to inflict had they never figured out how to navigate the globe successfully.

@brelson that's a good one!

There was navigation before the compass, and I'd say any harms are indirect like a bicycle, which you could theoretically ride to someone's house to do a murder.

@mulegirl Legos?
@soundclamp I love legos. I think the fact that they are made out of plastic that takes 1300 years to degrade is an issue for my calculus.

@mulegirl Modern textiles, like polar fleece and breathable waterproof fabrics.
