What is your argument? Android is one of the most successful software projects of all time. It seems easily monetizable.

First put five people from the same company in a room with an adjustable thermostat and see what happens.

“Scientists have proven octopuses are complex, intelligent creatures who can feel a full range of emotions,"

These animals get a lot of hype for their intelligence lately, but surely cows and horses are more intelligent, yet still farmed and eaten.

If there is a 'god equation' it will almost certainly include a+b=c because we use it all the time to describe "diverse biological systems with vast implementation constraints".

This article is lacking originality and insight to such degree that I susupect it is patentable.

Sure :)

Most people cannot hold themselves (or their loved ones) accountable because we love ourselves and accept any excuse at all. This is the main appeal of personal trainers imo, to tell you to do what you already know you should.

Great idea. Also, thank you for making it human.

There are bosons that carry charges and/or mass like the weak bosons and the gluons. There is nothing in principle about bosons that would make them incapable of building logic gates out of them.

Some advanced civilization (future us) may use them. Even photons interact with each other a little bit due to QED.

Possibly because being in the business of trying to turn iq edge into money, not data edge into money.

A myopic defocus screen effect. Some gradient descent may be used to approximate a difficult mathematical function, but not AI in any meaningful way.

Applying multiple svg filters on top of each other in the needed order resulted in Firefox dropping the filters completely. I filed a bug for Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1873644 As soon as it is fixed there will be a Firefox extension, and the live demo on the site will start working.

The Mac version is in progress.

I will submit a request for exception/deeper review to the vendor that flagged the exe. I can also offer a full refund and reversal of the sale if you can not make use of the software at the moment due to your security concern. The exe and the installer are signed by the company I established for the project Refractify LLC.

Thank you, 1. As long as the myopia is progressing there is an opportunity to slow that and avoid complications of high myopia. While screen altering may in principle go beyond the effectiveness of optical devices for myopia control as we can provide arbitrary input to the retinal neural network, realistically myopia reversal for adult humans is not considered achieveable. Intervention should ideally be started as soon as possible. In fact there is the possibility of delaying the onset of myopia or fully preventing it for some future generations, but obviously we are a long way off from there in terms of clinical studies.

2. I think undercorrection is somewhat related. I have not yet read the study you linked, I usually refer to this review for undercorrection. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9213207/ I think it would be possible to achieve some results that way as some of the studies from the review suggest, but in practice it is difficult to precisely control the amount of myopic defocus on the retina that you get that way. Most of the time you get no myopic defocus at all due to accomodation and with strong undercorrection you risk losing the visual cues to the sign of defocus, which results in deprivation myopia. I think this is the reason that MiSight contact lenses are known to be effective, while naive undercorrection has mixed results at best.

If you induce myopic defocus by plus lenses you create an urge to move the screen closer, which removes the effect. We need to achieve the right defocus on the retina. Wheres with the software solution you can not "cheat" by moving closer.

Most optical properties of myopic defocus can be simulated on screen. Since the processing is on the retina, screen altering can be effective. Android app is in progress.

Thank you for the kind words. Smart phones are in progress, yes. Apple will possibly not like it as it alters the look, but we will try and see.

Since last summer I learnt some about emmetropization, visual cues to myopia control and the state of consumer software business. Please let me know if you would like to discuss anything.

In the EU if a software is influencing diagnosis decisions of a doctor in any way it needs to be registered as a medical device software. Probably a similar regulation can be expected in the United States too.

I work on such a project. It projects myopic defocus on the screen based on longitudinal chromatic aberration. The project is in pre-clinical stage. You can try it out at https://refractify.io/ . It is aimed at recreating the visual myopic defocus signal that makes lens based myopia control techniques work. There are some promising results on animal myopia models.
