How to actually make a billion (the YC formula):
1. Work hard to build a great product.
2. Get VC money.
3. Offer great product for free by spending ridiculous amounts of VC money.
4. Switch to a paying model once you have starved any competition with your free offering.
I recently joined a local game jam with the intent of showing off my 2D engine. Halfway through, I realized I didn't have a way to properly destroy game objects. I realized it after messing up my cooldown timer and accidentally spawning a few thousand projectiles. It's something I knew I had to do that but I kept pushing it back to work on more interesting (but less critical) stuff. Now I am building a very simple hack-and-slash game and adding engine features as needed. Documenting the process here[1] for anyone interested.
Translating the OpenGL code to Metal/Vulkan will likely be a lot of work. Have a look at [1] which is something like tutorial 1 in the series. Its super verbose!
OpenGL 4.1 was silently supported up to some version of OSX. Not sure if that is still the case. You could try changing:
import github.com/go-gl/gl/v4.6-core/gl
to
import github.com/go-gl/gl/v4.1-core/gl
and see if it works.
Is it a surprise that an education system targeting the mean produces results close to the mean? It's like training for the marathon by only doing 2 mile runs and then saying people's ability to run long distances shows little variation.
I think this is one of those issues that are presented as a hard/nuanced problem but really isn't. Single use plastic can be banned the same way lead paint is banned. That's only hard to do because of lobbying by Coke&friends. There is some inconvenience for the consumer, like having to return our glass bottles or bringing reusable containers to the supermarket but that's all doable (proof: that's how it was done before). The hard part is forcing corporate to take a profit hit.
It will put very strong pressure during the transition with a few young people supporting a larger aging population (see Japan). It's also opposed by capitalists as it goes against the infinite growth mantra (see for example Musk's comments on the subject). More importantly, it won't do anything in the short term where we need it urgently.
Lets set a new standard: if it doesn't run on raspberry Pi don't ship it. Not running on a Pi should be a rare, special-case exception (e.g. need to train a model on GPU).
