Sci-fi writers have dreamt of and described systems and machines like JARVIS or HAL or what-have-you, they haven't built them yet
And i'm tired of waiting for them to build it.
It's not like people are sitting on their asses doing nothing, or don't daydream about all the exciting things that you do. It's just an *extremely* long road ahead, and there is likely no "royal road" to it either.
And btw, we don't have the "same type" of things. Take 3D engines for example. They might seem the same to you, because you don't know what it takes to make one. A 3D engine runs on a machine with finite resources like CPU and RAM, and built by development teams with finite resources like team size, time and money. Compromises need to be made. Naturally, you'll have to decide which compromises you'll make depending on your goal. Some 3D engines focus on amazing animation, others on amazing lighting, some are better than other in physics, others handle large, streaming worlds better. An "ultimate" system/machine that takes care of every type of need is not an "idea", it's a wish. A magical reactor that harvests energy out of the vacuum is also not an idea, it's a wish. You get my point. You can spend all your days wishing for it, and imagining the day you'll have it built and be showered in global admiration and money, that won't make you any wiser on how to actually build it, or whether it's even desirable to build such a thing.
In short: Go write a pong clone first. (and if you don't, because you think it's mundane and "beneath" you to do the same work as all the rest "little people" before you, it's no skin off my back, it's your potential you're wasting pipedreaming, not mine)
