I am already living in this inevitable "future" that you speak of.

In this city, ranked with the highest light pollution in the world, has already been completely replaced islandwide with the following led specs:
Extremely bright light of over 1500nits
7500kelvin
PWM 200 hertz with 99% modulation / 2000 hertz but with even higher brightness intensity
They can be found in everywhere with every 3 - 6 feets (or 1 - 2 meters), across the entire city. Streets, shopping malls, subways, stations, you name it. During the covid lockdown they took the opportunity to renovate ceiling lamps to leds. They even put neon signs and digital bill boards with the above led specs everywhere as well. I have to wear sun hat indoor as their ceiling is typically only 2.5 meters low and I stand at around 1.9m. Therefore, the led is right in my central vision, and only around half a meter from my head.
To cope with this,I have to wear shades (to cut down on the glare and brightness intensity) and 98% blue light fitover glasses(to reduce my sensitivity to flickering) wherever I go outside.
Occasionally, I could even see the led light source flickering in my peripheral vision. That's because while their switch to cheap LED have increased brightness by 2-3 times, they kept the PWM hertz low and modulation high to reduce overall electrical energy consumption. Being able to percieve brighter light flickering in the peripheral vision is due to critical flicker frequency.
Yea, that's just how bad and awful it is. It's inevitable.
