I guess we might actually have similar feelings, except, you say "only speed", and "only economics". Only time and only money. As if those aren't two of the most valuable currencies on earth.
Yeah, because I can see some of my own thoughts and experience from a long time ago in your words, and my experience tells me loud and clear that they're outdated and wrong.
Only because I do not share your point of view it doesn't mean I lack experience or skills.
You are pretty fast at jumping at conclusions.
