I agree with the latter part but not the "knowledgeable" portion of the first sentence only because of what Homeles says.
Being an enthusiast is about the journey, and electing to take the journey of one's own volition, and not about the destination.
Look at me for example, it was only just 2yrs ago that I wrote up this
completely wrong POS of a thread on clockspeed and Vcc versus power consumption D:
Why did I make that thread? Because I enjoyed the process, I was enthusiastic about the journey. Why was it wrong? Because despite having a PhD and having years of experience with semiconductors I totally managed to brain-fart and forget to capture the effects of temperature on power-consumption
Come back 3 weeks later and you
have this thread, correctly incorporating the device physics that belay the impact of temperature on power consumption in addition to operating voltage and clockspeed.
Knowledge was generated in the process, but would I have bothered to undertake such an endeavour if I wasn't enthusiastic (curious) to see what I could find out with those tests?
I think most people in this forum have a unifying commonality, we are all curious about stuff going on with computers and technology. Be it the process tech, the business management aspects, the economics, the software side of things,
and the hardware of course etc. We are all here because, unlike the people who wouldn't take the time to be in these forums, we find it (the journey) of discovering things we previously did not know about to be well worth the time invested in being here. We are enthusiastic about it.
