It's bananas to me that questions like these could be unanswered even 5 years after the business started. This possibly cannot be the most efficient way for finding new solutions and "disrupting" stale industries?
Those are rookie numbers, Discord is coming up on 10 years old and has made zero dollars to date, yet is supposedly considering an IPO soon.
The thing is, the people with far more information than we have, and with actual money on the line, think this is a good use of their money. They're not always right, of course, but the industry as a whole is profitable and is innovative and "disruptive".
So, yes, this can be a good way for finding new solutions. The most efficient? IDK but it's the best we've come up with so far.
