The patent for the Teletype machine was issued in 1907, any variation thereof, up to and including paper punch cards would probably invalidate the patent.

Your immune system is virtually bullet proof under those circumstances

Cheap steel bikes can weigh north of 40 lbs, yep. Heavy Aluminum bikes can weigh north of 32 lbs. My roommate has a folding aluminum bike, it's 36 lbs before you add on the rack, fenders etc.
 
I have a late 70's lugged steel frame bike, it weighs about 24 lbs, probably closer to 26 now with the rear rack and fenders.
 
By comparison my aluminum road bike weighs about 21 lbs, only a 5 lb difference between the two, but 19 lbs lighter than a cheap Walmart bike! A modern $1200 aluminum bike can weigh less than 18 lbs
 
TL;DR not all steel bikes are made the same.

You don't use your arms to support your weight on a road bike, you use your "core" torso muscles. Try riding in an upright position until your core strengthens enough to ride in an aggressive road bike position.

Yes, Titanium is not a ferrous material.

Your ratios are a little skewed, but this already happened with the mechanisation of agriculture. Art as a profession didn't exist 4000 years ago, then we had plows attached to oxen, and nowadays we have so many artists people find them annoying

Cuba recently (last 18 months) had an undersea line laid from Cuba to Venezuela. Previously they could only connect via Satellite link.

It's still an achievement. If you look at it objectively the middle man only exists to expedite sales of cars from the manufacturer to the end user. If it's now more efficent to get the product to the end user directly than working through a proxy, you've cut out a step. In the era before instantanious cheap/free communication the middle man was an important center of local product knowledge, now we have wikis and fedex. I can troubleshoot and order an alternator for a rare car on the internet and install it myself, I don't need the specialized knowledge of the BMW dealership to do this for me anymore. Electric cars have even fewer moving parts to maintain.

Liquid oxygen (part one of a two part fuel solution these devices use, part 2 being highly refined kerosene, or "RP-1") requires specialized holding facilities and due to it's temperature can't be stored on a truck for more than a couple of days in any usable quantities, which means their "home base" can't be more than 10-15 miles away. That's still a big area, but pretty easy to monitor with satellite photography.

Germany is a snow covered, overcast hellscape for a decent chunk of the year (they border Denmark, Poland, Switzerland, etc) yet they manage to lead western Europe (Sunny Italy, Greece, Spain, Portugal included!) in solar generation. Do you have citation for those line losses? Everything I've read says single digit line losses, even trans continental.

30 square miles of unfarmable salt flats, solar is a pretty good use of the space, really. Not to mention jump starting the local solar panel industry something fierce.

Probably using the same Halliburton designed-and-tested valve technology as "too big to fail" deep water horizon.

I actually had learn what EBCDIC was to use it in a NEW production process in October last year (2013). Nobody on the project knew what it was (we're all in our 30's), but it was easier to learn EBCDIC than try to rewrite the mainframe process that was spitting out the EBCDIC files. Except one guy who knew what it was and kept correcting our pronunciation of Ebb-kah-dic.

Win 8, 8.1 still does this, but you can override it using a powershell command, otherwise there's a GUI function that will trigger the powershell command for you.

If China uses my information to come up with a cheaper way for everyone to sit around in their underwear drinking beer reading news on the internet, where do I sign?
