> Could lead to significant efficiency gains for EV's, because 1/4 of the motor weight means better power-to-weight ratio... a lot of things will automatically get better.

EV motors are already lightweight. The electric motor in a vehicle like a Tesla Model 3 already weighs less than you do. Reducing that one component by 75% would be a weight savings equivalent to about a half of a passenger.

Not a significant efficiency improvement for vehicles that weigh over 3000lbs (or double that for many EVs).

Every little bit helps, but this isn’t a game changer.

I would expect that lighter motor components would potentially allow weight reduction in load bearing components. Not an advantage for SUV-type cars, but for light and ultralight vehicles it could add up to more weight saving and longer ranges.

> There are good use cases for machine learning, AI, etc. But sadly, the best ones are masked by the hype-train AI junk that is either useless or incredibly expensive in comparison to the amount of money being charged for it.

so ive been in the industry ~8 years now, and this is the exact same discussion that was held during the NFT/blockchain hype. this cycle seems inevitable for any new disruptive tech.

lucisferre · 3 months ago

Does NFT/blockchain actually have a cycle? I have not seen any real killer use cases.

AI may be overhyped but the actual use cases and potential ones seem very clear.

Can you please not post like this to HN? It's against the site rules (https://news.ycombinator.com/newsguidelines.html).

The idea is: if you have a substantive point, make it thoughtfully; if not, please don't comment until you do.

Fair comment.

My take is...

No one needs an ORM: https://dev.to/cies/the-case-against-orms-5bh4

The article opens with "ORMs have proven to be useful for many developers" -- I believe the opposite is true.

lucisferre · 4 months ago

I agree with this as well. I started my career at the height of ORMs. Most software developers were only learning the ORM APIs (which of course all differed significantly) and very few were learning SQL outside of the bare basics.

ORMs, like all abstractions, are a leaky abstraction. But I would argue because of the ubiquity and utility of SQL itself they are a very leaky one where eventually you are going to need to work around them.

After switching to just using SQL in all situations I found my life got a lot simpler. Performance also improved as most ORMs (Rails in particular) are not very well implemented from a performance standpoint, even for very simple use cases.

I can not recommend enough that people skip the ORM entirely.

AI is only different if it reaches a hard takeoff state and becomes self-aware, self-motivated, and self-improving. Until then it's an amazing productivity tool, but only that. And even then we're still decades away from the impact being fully realized in society. Same as the internet.

lucisferre · 4 months ago

Realistically most people became aware of the internet in the late 90s. Its impact was significantly realized not much more than a decade later.

So not PowerBI then. Or really any BI tool.

My favourite example of not "fast" right now is any kind of Salesforce report. Not only are they slow but you can't make any changes to the criteria more often than once a minute. Massively changes your behaviour.

Sama clocked this way back. He has used this exact analogy - that new GPT models will feel like incremental new iPhone releases c.f. the first iPhone/GPT-3.

lucisferre · 5 months ago

Seems a bit early to use that analogy though. Early iPhones upgrades generally had significant improvements in almost all specs.

I think the article is in the general category of articles suggesting that planes would work better if they flapped their wings.

AI's "think" like planes "fly" and submarines "swim".

Does it matter if a plane experiences flight the way an eagle does if it still gets you from LA to New York in a few hours?

lucisferre · 7 months ago

Much of the discussion of AI flirts with science fiction more than fact.

Let's start with the fact that AGI is not a well defined or agreed upon term of reference.
