Well, the thing is that 3 years looks like "too long" but eventually the spec is held by the timeframe of having actual silicon. Even if it's not 1 year or 2, at least is not 5 or 7.
That's probably the problem of standards. Everyone has to agree to a new spec, instead of a company offering double the PCI Express bandwidth and latency that, low and behold, only works on their hardware and will charge for royalties.
3 years look like a lot, but it's cheaper than vendor lock-in, which everyone has afraid of since is in that moment your business is controlled by other business.
They’re not known for big projects. Except Callisto Protocol which flopped so hard they will put their hands on whatever has more than 7 figures.
I while I’m kind of happy for the people who can still have a jobs, I fully expect they become a shell from their former selves (cut jobs) and make freemium crap.
