I switched mostly to using an RSS reader to see the headlines, and then read what is interesting. Plus I follow several writers that I trust (eg. Heather Cox Richardson).
So, number of software developers doubles roughly about every 5 years. So if you have been in the field for 5 years, half of the developers will be younger than you, if you were in the field for 10 years, 3/4 will be younger than you. You can do the rest of the math.
I've been working as a developer for 40+ years, so most other developers are younger than me. Although, on my current team there are two people older than me.
As I recall, Assembler was the first "no-code" tool. After all you could get rid of all those pesky programmers who knew all the number codes for instructions. Anyone could write "ADD R, R2". See!
There is a great advantage to an e-Reader (like Kindle) in that you can turn any book into a large print book. As you get older and you eyesight gets worse this is no small advantage, since you can continue reading the stuff you like.
There are some magazines (looking at you New Republic) that we stopped subscribing too because the font is too small to read - I can still see it, but trying to read it causes eye strain.
The Poles certainly got the ball rolling (see http://www.codesandciphers.org.uk/virtualbp/poles/poles.htm), but the organization at Bletchley Park took decryption and analysis of Enigma traffic to an industrial scale. By the end of war Bletchley employed around 10,000 people. See Alan Turing's and Gordon Welchman's biographies for more details.
The story of the Enigma is quite complex. But by 1941 the Allies knew how the machine worked (there were commercial Enigmas sold before the war). The Naval Enigma was somewhat more secure (more rotors to choose from) and obtaining the daily setting book would be the most important thing, not the machine itself.
Polish mathematicians broke the early Enigma in the late 1930s (http://www.codesandciphers.org.uk/virtualbp/poles/poles.htm), they passed their information to the British in 1939 and that was used as a starting point of the work at Blechley Park.
If you are interested in the details, check out the book "The Hut 6 Story" by Gordon Welchman. He was a peer of Turing who worked on the Army and Air Force Enigma, while Turing worked on the Naval version.
Of course Turing's biography by Andrew Hodges also has a lot of details how the Engima was broken.
I don't want to get my news from social media.
