I do not believe there will ever be 'driverless' trucks, any more than there will be 'driverless' cars. The safety risk is too great, especially when you're talking about a vehicle with a combined mass of over 40 tons hurtling down the road at high speeds. The potential for dozens or even hundreds dying because hardware or software went haywire is just too great to ignore. There needs to be someone there to at least hit the brakes.
My bottom line: You want to preserve your youth? ACT LIKE IT. Don't allow yourself to 'calcify' in any way, physically or mentally, and you won't. Keep reading, keep learning, keep hearing and seeing new and different things, and for fuck's sake keep moving. You let your body turn to shit? Your mind will soon follow. And vice-versa.
b-b-b-but I have to have constant stimulation or I'll cry!
Get over it, Nancy. People will eventually get tired of having to pay for 'streaming services' one way or another, and they'll come back to free broadcast radio.
Bracing for the inevitable hate that will follow..
Say what you want about the man, but he's probably the closest thing to a real-life Tony Stark as we're going to get. In a world that seems to otherwise be content with the status-quo, he's pushing the envelope and bringing us the future of things. THAT'S why.
