Firstly, all farmed cattle have been bred to be farmed. They are similar to bovines from several thousand years ago but certainly not the same any more. Breeding will have included selection for being relatively sedentary and not needing to roam a great deal. Cattle in fields do not suffer from the kind of mental issues that afflict Orcas.
The tank for an orca is significantly smaller than the equivalent field for a cow. Tanks have got bigger but they are still small for a fast moving and powerful animal.
Orcas are predators, cows are not.
Ultimately, whilst cows do have a short life, they are generally treated quite well until the point at which they are killed.
To be honest, a comparison between the way we treat cattle and the way we treat orcas is not great as they are really quite different animals.
In one other respect, Linux is also very successful - smartphones and other mobile devices. Sure, it's not the GNU/Linux we were expecting but the far is that Linux is in the palm of a lot of hands and this is still increasing.
I do have reservations about driverless cars but I can see the potential benefits as well. My main concern, and one I've yet to see sufficiently well answered, is what happens when accidents do occur and that they are the fault of car or its software? Who's liable? If its my car, I've not driving, I've had the car properly serviced so surely its not my fault.
I feel obliged to mention that the newest generation of hypercars are hybrids with relatively modest electric-only modes and in reality use the electric motors to support the ICE.
The problem here is that there probably are some legitimate reasons to be concerned whilst others you can probably ignore. There is no doubt in my mind that the energy providers will ultimately find a way to exploit smart meters to their advantage. For me, I hope that I will improve my efficiency and increase my self sufficiency through improved insulation and home generation such that the providers will become increasingly irrelevant. Granted this is not something everyone can achieve although I imagine most would aspire to it. However, the hope is that a prevalence of alternatives plus a diverse market will keep the providers in check.
Being worried about RF radiation is probably nonsense but I've seen it tends to be a common policy of those who want to convince people that there is an overwhelming reason to oppose something. Not just one or two arguments but a significant list of reasons, many of which are untrue.
For me, both Sputnik and the Moon landings are of equal importance. The Viking landings are also high on the list as are the amazing discoveries of ther above mentioned robot missions. The moone landings got a lot of publicity during the cold war and I think that has caused bias in many peoples impressions.
