Not sure a single industry manufacturer is a good comparison. We wont really know til closer to the end of 26.

You do realize that that's more than 15 year-old technology in that car, right? Because he's solely speaking about the Roadster and that hasn't been produced since 2012.

So, and anyone with superior knowledge feel free to school me, shelf life and installed life are a bit different. Caps will die on the shelf if not used as they will slowly leak energy until they die. So shelf life is meaningless to caps used once in a while.
Regarding operating lifespan, what I see says that automotive grade caps are built to a much more robust standard that regular electronics. Of course, the ones you might use for EV uses are above and beyond that. Modern Tesla inverters look quite a bit different.
Teardown expert Sandy Munro compares Tesla, Nissan, Jaguar inverters - Charged EVs

I've seen Adrian's Digital Basement / Tech Tangent's and Usagi Electronics ' reforming ' old beer can sized Caps from the 1950's / 70's in old main frame equipment ... if they have not been leaking they work just fine
I've had several high end gaming computers whose board caps were Military grade NONE Electrolytic Caps
I would expect HIGH END [ or electric ] vehicle manufacturers to be using similar ....

Meanwhile my 2006 Toyota truck is still running like a sewing machine.

Which was produced after Toyota had what, 50 years experience in making a type of machine that has been in existence for another 50 before that?
My point being that comparing the very first product of a brand new company spending less than Toyota probably spends on marketing alone for one new model to the product of over 100 years accumulated knowledge isnt really fair.
The Roadster wasnt designed to be a mass market workhorse. You need to get a new Model Y to get the best comparison. Then check back in 20 years.
I'll note what one Toyotas response to the Model Y was.

So you can do it, but its not a thing most would.
My point was that the idea that caps are gone at eight years was a bad take on what Gruber was saying. But for most things, shelf life is aways greater than service life. So I see where Kyle made the misconception.
yeah I was basically agreeing ... decades old caps can be ' reformed ' after not being used and function fine
the other point I was hoping Tesla and others use high quality caps that do not have a shelf life aka Electrolytic cap types that leak over time

Can't speak to others. But I'm sure they are using auto grade caps at least. Munro and others usually refer to Tesla electronics as military grade.
i’m surprised it’ll run.

The specs for electronics are pretty tough.

If I may ...
For your consideration ...
This fella to just too cool. Hard to listen to someone that wear sunglasses indoors. Does he think wearing them makes him more intelligent and enlightened upon the subject?

As a consumer why would I care who has had longer to "work on it"?
Chrysler has been in the game a very long time also, but can't seem to make anything that lasts as long as Walmart's bread does.

Electrolytic caps have a higher charge density, the reason they are used.
I bought a super capacitor about 10 years ago to be used as a very short term UPS due to battery restrictions, worked great, cost over $30k but now it needs replaced.

Use vs shelf, use can be in hot/cold generates heat from use etc vs shelf is a much more controlled environment.So, and anyone with superior knowledge feel free to school me, shelf life and installed life are a bit different. Caps will die on the shelf if not used as they will slowly leak energy until they die. So shelf life is meaningless to caps used once in a while.

Recently had a 20ish year old rack mount computer have a capacitor explode, it was mounted in a van that was parked in the hot/cold etc for the entirety of its life, thing was about the size of a shotgun shell and sounded like it when it went off. The exploding cap took out one of the Pentium 3 processors on the MB.

As a consumer, you should be aware if you are buying the first gen cutting edge of anything has drawback and not expect that to compare to century old refined tech. Which was my apples to apples point. A limited run (2,500 made) high end first gen EV sports car built largely on adapted equipment from others.
Lets not pretend Toyota doesn't lay engineering eggs from time to time.
Taco frame rust
Tundra and Lexus engine replacements
BZ4 wheels falling off (only 260 were sold with that condition)
500,000 Tundras with a loose bolt that could let a part of the rear axle assembly come loose.
Every complex object made by humans is subject to issues. Every single maker has issues.

More people select a car based on the color or how pretty they find it than what makes it up. Most car purchases actually have no research or forethought before they are made.
