Yes, imagine when cancer becomes a solved problem, and oncologists react online by lamenting the end of their life's work. They'd be viciously scorned and ridiculed.
Claude code 2.1.16x (released 1+ year ago or so) is quite ok, dynamic workflows off. Do not use the latest version, they burn a shitload of tokens and are slow.
Light being from a laser does not automatically make it more dangerous. You can even shine a regular class IIIa laser pointer, with warning label still intact, directly into your eye and you'll blink long before it will do any damage.
The issue is intensity of light. These retinal projector lasers are not intense enough to damage your eye. A regular light at the same intensity as a powerful laser would damage your eyes just as much. It's just a lot harder to create a regular light that can reach that level of intensity.
I think the tricky part is if they start cranking up the intensity to counter it being scanned sequentially over a larger area...
First, what is the fail-safe in case the scanning mechanism fails? I.e. is the intensity safe if the beam becomes stationary? Or does it guarantee it goes dark when not properly scanning?
Second, what is the safe intensity limit for the brief visits to each target pixel area? As the scanned area increases, you need higher intensity to maintain the same visual brightness with a shorter exposure for any one spot. At some limit, is the pixel to area ratio too low and this intensity too great?
Third, does the optical path through the cornea and lens have any hot-spot where you have to also worry about peak flux with this projection technique?
That's the first thing i have searched the current blue screen have already caused enough damage to eyes. but ig it's still in early prototype and i would be appreciated if they provided the affects that it might causes to eyes.
That has been proven to be false, too. The blueness of the light doesn't matter, the brightness does. Any bright light might affect melatonin production and circadian rhythms.
Selling blue-light filter coatings is a big business, though.
"While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours)." https://www.health.harvard.edu/healthy-aging-and-longevity/b...
"Evening residential illumination possesses the capacity to impair sleep quality via the suppression of endogenous melatonin production, a process largely driven by short-wavelength (blue) light." https://www.nature.com/articles/s41598-025-29882-7
"Blue light waves come from fluorescent and LED lights and back-lit electronic screens on televisions, computers, tablets, and cell phones. Remember, exposure to these lighted screens during the sensitive period can make it difficult for you to fall asleep at night or can wake you up too early" https://www.cdc.gov/niosh/work-hour-training-for-nurses/long...
"Blue light had stronger suppression effects, particularly in younger participants and men. These results underscore blue light’s disruptive effects on circadian health and highlight red light as a less disruptive alternative for nighttime environments." https://pmc.ncbi.nlm.nih.gov/articles/PMC12113466/
I find meta-analysis are better for understanding the current state of research on a particular topic.
"A systematic search of PubMed, Scopus, and Web of Science identified randomized controlled trials (RCTs) from 2010 to 2024. Eligible studies enrolled adults using BBGs before bedtime and reported actigraphy-derived outcomes. Random-effects meta-analysis was performed using the generic inverse variance method. The review was registered in PROSPERO (CRD420251034611).
Results
Three double-blind crossover RCTs (n = 49) were included. BBGs showed a non-significant reduction in SOL (MD = −4.86 min; 95% CI: −20.23 to 10.52; p = 0.54) and a non-significant increase in TST (MD = 8.75 min; 95% CI: −35.31 to 52.82; p = 0.70). No significant effects were found for SE (MD = −0.61; 95% CI: −7.58 to 6.35; p = 0.86) or WASO (MD = −1.47; 95% CI: −14.94 to 11.99; p = 0.83). Heterogeneity was low (I2 = 0%).
Conclusion
BBGs may provide small improvements in sleep, but current evidence from RCTs does not support significant effects. Larger, well-powered trials with standardized protocols are needed."

given that phonescreens do not really dim the brightness and still flash lights in your face at full power just at slower intervalls does in a way confirm the point.
(See PWM dimming)
And a redlight filter just lowers the total brightness by shutting down the blue LED
that addresses the parent's last sentence, about blue light glasses, but not the "The blueness of the light doesn't matter" part, which is what all of my quotes addressed.
IBM was working on this in the early 90s[1], and had working demos in the late 90s/early 2000s. I'm pretty sure we would have heard about health risks by now
