With telecom, we benefited from skipping generations. I got into a telecom management program because in 2001-ish, I was passed by on a village street by a farmer bicycling while talking on his cellphone. Mind you
my family could not afford cellphone call rates at the time.
In fact, the technology was introduced out here assuming corporate / elite users. The market reality became such that telcos were forced kicking and screaming to open up networks to everybody. The Telecom Regulatory Authority of India (back then) mandated rural urban parity of sorts. This eventually forced telcos to share infrastructure costs (share towers etc.) The total call and data volumes are eye-watering, but low-yield (low ARPU). I could go on and on but it's just batshit crazy.
Now UPI has layered on top of that---once again, benefiting from Reserve Bank of India's mandate for zero-fee transactions, and participating via a formal data interchange protocol and format.
Speaking from India, having lived here all my life, and occasionally travelled abroad (USAmerica, S.E. Asia).
We, as a society and democracy, are also feeling the harsh, harsh hand of "Code is Law", and increasingly centralised control of communication utilities (which the telecoms are). The left hand of darkness comes with a lot of darkness, sadly.
Which brings me to the moniker of "third world".
This place is insane, my friend --- first, second, third, and fourth worlds all smashing into each others' faces all the time. In so many ways, we are more first world here than many western countries. I first visited USAmerica in 2015, and I could almost smell an empire in decline. Walking across twitter headquarters in downtown SF of all the places, avoiding needles and syringes strewn on the sidewalk, and avoiding the completely smashed guy just barely standing there, right there in the middle of it all.
That was insane.
