So you can imagine what happens if you betray your group: you will be a kind of outcast. Something no Japanese can live with easily.."

I might contrast Japanese loyalty with the West's Oath of Fealty, which requires loyalty in both directions.

Are you being sarcastic? If your idea is so amazing, and you have it well-protected by patents, why not open source the implementation and fund development/marketing through donations?


--- Quote ---Not only that, but if you take a look at the another online fitness service like that of Zwift, they have just received their 5th round of funding and it was above 500m$.  I dont know how a company in business for almost a decade can achieve continuous funding, basically they aren't making any serious profit

I'm being serious, my AI workout music tech does hijack your brainstem (Yes, there is more to it than that...).  I need 50 full time employees to bring a final usable product to market.  On Kickstarter, there are only around around 10 successful crowd fundings above 10m$, all of which had known artists / novelists / game devs who already had an active fan base to feed from.  Without that, I will never get what I need as 50 employees + facilities + international legal council + 5 additional international patents to be filed makes 10m$ seem too small as it will take 4 years before I expect to make profits and everyone needs a proper salary.  I'm sorry to say open source cannot cut it, I need the equivalent of a small game-dev studio.

Remember these: The blue LEDs that existed before the current InGaN blue LEDs...



I remember at the time that my Volkswagen Passat car had a blue 5mm led as an indicator in it's dash board.  It had a blue tinted lens.  I believe it was there to indicate that the high-beams were on.  Boy was it dim...

Beat me to it. I admit, I haven't watched the Veritasium, because I lost interest in is channel awhile ago, but just seem that one.

Yes, I remember those old. expensive blue LEDs. I think I still have a few somewhere. I was fascinated by lighting when I was a child. It got me into electronics.
