My prediction is it will make our cities worse. In 30 years every family will want one self driving car per person in the household

When I was working for the automotive industry their models and projections suggested that ubiquitous self-driving cars would reduce the total market for cars to ~15% of its current size. As in, sales would drop by 85%. The addressable market for automotive OEMs is set to undergo a dramatic reduction in size.

Few automotive companies have a coherent plan for how they were going to survive that existential risk.


People will still be doing about the same number of miles per year, and cars will still last a similar number of miles. So if a ride share car does 10x as many miles per year we need 1/10 the cars, but they also last 1/10 as long, so it evens out.

Sure they'll get slightly more miles out of a ride share car, but the number of miles will also go up do to dead heading and because cheaper/better transportation causes prior to use more of it.


Sorry, but at the current price of Waymo rides that just can't happen. They become more expensive than leasing a car at something like 8 rides per month (as in, get into a Waymo, expect to pay $60 per ride)

Oh and this price was going up, not down.


Current price no, but future price maybe. There's already a market for it, and a lot of pent up demand.

This justifies wholesale fleet purchases of EVs. A competitor could come in with a cheaper model. There will be a lot of players who want a piece.


Isn't this the same as saying that if cars drop in price 2x the opposite will happen?

> They become more expensive than leasing a car at something like 8 rides per month

Does this include fuel, insurance, repair, parking, registration, maintenance, etc.?


If they can figure out how to really take advantage of economies of scale, and drive the costs down quite a lot -- the desirability of car ownership will drop dramatically.

Everyone I know under 40yo already professes to hate driving and hate car ownership.


Owning a car and living somewhere you have to use it for day to day everything is tedious. But the option of one for the weekend, trips out of town, into nature is ultra valuable, enough so that it's worth it to have a car sitting doing nothing during the week for us, even in a well connected large city, in a walkable area.

At present or I suspect future costs, any kind of taxi for an out of town trip (without any rail option) of 50-100 miles is way too expensive to consider, we'd sooner hire a car, if it was slicker and more convenient. But hiring a car anywhere but an airport terminal needs a trip to the hire place, and needs to start and finish when they're open to avoid spending an extra day or two of hire. Plus time taken on paperwork and insurance faff could easily be an hour.


Why?

At worst you can just pay extra to have a smaller or more luxurious private self driving taxi vs. something more like a bus, shared with others. The appeal of owning and having to maintain something like this is nil. You're not in control, there's no ownership of the driving experience, and if appropriately compliant with the law, they should all drive the same speed.


Guaranteed availability and being able to leave stuff in the vehicle would be the main draws. Even privately owned, they'll still have subscription fees.

if you can steer an LLM to write an application based on what you want, you can steer an LLM to write the tests you want. Some people will be better at getting the LLM to write tests, but it's only going to get easier and easier

because a lot of people still prefer voice communication over navigating the internet and filling out a form


same!


yeah this was a weird article and largely a waste of my time


Has anyone else here banned exceptions (for the most part) in less critical settings (like a web app)?

I feel like that's the way to go since you don't obscure control flow. I have also been considered adding assertions like TigerBeetle does

https://github.com/tigerbeetle/tigerbeetle/blob/main/docs/TI...



Most large open-source projects ban exceptions, often because the project was originally converted from C and is just not compatible with non-local control flow. Or the project originated within an organization which has tons of C++ code that is not exception-safe and is expected to integrate with that.

Some large commercial software systems use C++ exceptions, though.

Until recently, pretty much all implementations seemed to have a global mutex on the throw path. With higher and higher core counts, the affordable throw rate in a process was getting surprisingly slow. But the lock is gone in GCC/libstdc++ with glibc. Hopefully the other implementations follow, so that we don't end up with yet another error handling scheme for C++.


Lots of games, and notably the Unreal Engine, compile without exceptions. EASTL back in the day was in part written to avoid the poor no-exception support in Dinkumware STL and STLport.


Basically all high profile engine teams I know of ban exceptions. They're worse than useless


Isn't github a rails app that heavily uses server side rendering?


Not any longer. The rewrite which destroyed performance uses ReactJS https://news.ycombinator.com/item?id=44799861

What is terrible is that new developers think that this has been the usual poor state of things...this is why Zig & others moving to alternate platforms is good.


I'll be honest, I don't use github often. So if they're wrong, well, they fucked up in their complaint that could be redirected to one of many other websites instead.


fair enough! To be clear - a rails app and a bloated js app are not mutually exclusive. From my observations though, github feels slow because it feels slow, not because of js shittiness


I'm still confused. Why not just pour a ton of resources into it since it's open source. I guess dev mindshare? It is a great product


Pouring a ton of resources into an open source project that raised $26m in VC doesn't guarantee that the project will stick around. Acquiring it does.


Buying Bun to ensure it sticks around doesn't pass the smell test unless they had very few months of runway left


Bun had four years of runway left.


I would be curious to see how Sonnet does. Their models are pretty solid when it comes to PDFs


Sonnet/Opus is being added shortly!


sonnet and opus are live now :)


Dang I was gonna get one with nano texture but the opinion was 50/50 everywhere so I went with the Devil I know
