Just curious, why do you hate elon so much?

Thats... displeasing to hear.

You don't use zero days immediately. You stockpile them for when the time is right. A quantum computer is the ultimate zero day.

The real problem is building a system that can survive noise, errors, and decoherence. Once you solve that, scaling it up is non-trivial but has a very exponential path.

Like, duh? Then you are going to be all high and mighty about your morals, but why did you take the $200m in the first place?

He makes big prenouncements, but once he gets in the engineering details... they cease to make sense. Tesla in tunnels makes more sense because they can be end to end. Instead of a hypoerloop, you can drive a cybertruck fast AF down a tunnel. (Again, tunnel boring is the bottleneck here.)

New roadster is on like revision 20+. They had 4 roadsters in 2018, each different from the last. Last i've heard on this, the roadster is going "to fly".I think what he means by this is they are going to add krypton, or some sort of thruster to the car. They don't want to launch the roadster to compete with the cyber truck.

Instant battery swaps were for rigidity purposes. If you cast the battery directly into the car, the battery becomes part of the frame, resulting in a much smoother ride. They did have a couple prototypes of Battery swaps, but they decided not to pursue it and instead focus on improving the megachargers.

Tunnels to replace all traffic was discussed above a bit, but he did do the vegas loop and is doing it for waaaaayyyyyyy less than any other underground system. Something like $42m for the whole vegas loop. I think the boring company has like 5-6 ongoing projects around the US. Did you expect him to do it over night? They custom built a boring machine, like 6 times over and are doing projects all over the US.

your car appreciating in value... I mean, they actually kinda did... If you had an early enough reservation on the model 3, you could make a big flip. Thats why they put a clause in for the cybertruck where you couldn't flip. Also, renting it out on E-turo was very profitable for the longest time. All jokes aside, cause i know that's not what you're talking about... Yeah, that's a bold face lie from elons part. Because latest models only are going to run on AI6 chip.

Semi Convoys are an awesome idea and could totally work. I mean... like i said, AI self driving is pretty good. Especially on freeways. Streets, not 100% solved, but i literally never have to disengage on the freeway. They just built an entire dedicated manufacturing facility that started commisioning this month for the Semi. You will see this alot more often. Obviously they'll still have human drivers, but i'm sure they can write some software to make this possible and provide some "draft effect" for the semis.
