This is all I can think of and it depresses me how exciting the video is about turning more materials into emissions. I get I have no power over these people building this, but I just wish they didn't make it. I don't want the world to keep building more amazing ways to burn things I or my neighbors will eventually have to breathe in.

Particularly when burnt to no purpose at all.

Natural gas turbines are pretty common (power plants, large on site/mobile generators) and the efficiency levels of these are the same as what you'd see in similar use cases. Turbines don't really care what they're doing (within reason), these just happen to share a lot of parts with a plane engine.

The cost issue is completely unrelated to supply or usage, there is a cyclic issue of power companies using their profits for lobbying in order to push through measures that allow them to further increase their rates. It is often far more than is publicly disclosed.

For example, last year in this state my power company made billions of dollars and claims they spent less than a million on political contributions. But if you look at their donations, grants, and development programs there is over a hundred million dollars mostly going to companies and nonprofits owned in part by the same politicians or their family members, as well as the municipalities where the policymakers live.

In my state the combined total of rate increases in the past five years for both electricity and natural gas is >1.5x compared to inflation. Each time it is framed in the press as a good thing "we reached a solid deal, for less than half as much of what they were asking!". Every year the profits exceed their expectations by a few percent, each year more people are having their power shut off.

Except the point of Boom’s post is to brag that they’re using plane engines.

Coal consumption has peaked there. Solar is growing explosively.

Which begs the question of why AI DCs can’t be powered with their own solar they build out themselves.

I can see some issues there. Spacex was in a unique position to do starlink as about the only cheap launch provider whereas there are many existing gas turbine producers. Also the gas turbine thing is a bit of a temporary fix to get power for the AI bubble. Longer term they'll probably use more environmentally friendly solutions?

Why would they switch to something more expensive long term?

> announcing Superpower, our new 42‑megawatt natural gas turbine

Is global warming solved? Last time I checked, I was to throw away my repairable ICE vehicle for an expensive unrepairable disposable vehicle in order to save the planet. Just curious how a 42-megawatt gas turbine is helping the planet.

A 2 GW DC only needs 48 of those things. About 11.5M tons of CO₂ per year. It’s always on full blast so everything must be calculated 100%.

A new Civic going 8,000 miles a years at will produce 2.4 tons. So yeah one new DC is 4,700 cars. Which you’re supposed to replace with electric cars that will be fed with a non-existent power source, which means apparently even more gas turbine power plants.

Most assumptions about renewables don’t account for continuous 24/7 loads. Stuff like storage doesn’t help with that. I have noticed very little talk about AI DCs varying their loads to match renewable generation from solar/wind.

Google + Zoom + Slack is 3 separate accounts. Corporate only wants 1 account.

Speaking as someone running a small business, and working with larger (200 employee) small businesses, this really isn’t the case.

Most places have Google Workspace now. It’s pervasive. Most also have Microsoft 365 in some form or another. People generally want GMail, not Exchange.

Syncing users between Zoom and Google is completely trivial as is automating onboarding and offboarding.

Paying 3 annual accounts is not much different than 1… and is a bonus if it leaves you the option to completely migrate off of on.

(Incidentally a pattern I’m seeing is a place has Google Workspace plus Zoom, and then employees buy their own copy of Microsoft 365.)

CRUD as a concept is flawed. It is more or less any computational system with input -> process -> output. Just as this abstract system can have any complexity, the same is true for any CRUD app.

You don't need Claude to write it. But you cannot generate solid web forms with the same speed. What usually would have taken you a few hours is now solved in much less time.

I doubt software will get cheaper though, requirements will adapt.

If I wanted to make a crud, I’d whip up my own little framework first (a few hours) and then cranking out forms would be almost trivial.

> These kind of tasks ought to be have been automated a long time ago

They have been, repeatedly, since the 70s. See dBase, Clipper, Microsoft Access, Hypercard, Ruby on Rails, stretching Wordpress to within an inch of its life, all manner of "no-code" things...

And, honestly, Excel. People do all manner of terrifying things with Excel, and it is unquestionably the most successful, and arguably the _only_ successful, "we can do this thing instead of employing a programmer" tool.

Generally, one of two things has happened. Either (a) the products of such automation become unmaintainable nightmares (common for the more automated approaches like MS Access) or (b) they become complex enough that they tend towards 'normal' programming (common with, say, Rails, where you could get a simple CRUD with basically just DSL, but realistically eventually you're gonna be writing lots of Ruby).

I feel like LLM-produced stuff is probably going to fall into column A.

Excel and Google Sheets are indeed where most non-programmers frequently come the closest to programming and actually create useful apps for themselves.

So what’s interesting is that Copilot is basically useless for this task, as is Gemini. How is Microsoft messing up this badly?

What do you mean when you say building crud apps should be automated?
trollbridge · 6 days ago
CRUD apps are ridiculously simple and have been in existence my entire life. Yet it is surprisingly difficult to make a basic CRUD and host it somewhere. The bulk of useful but simple business apps are just a CRUD with a tiny bit of customisation and integration around them.

It is true that LLMs make it easier to build these kind of things without having to become a competent programmer first.

Had the cost of building custom software dropped 90%, we would be seeing a flurry of low-cost, decent-quality SaaS offering all over the marketplace, possibly undercutting some established players.

From where I sit, right now, this does not seem to be the case.

This is as if writing down the code is not the biggest problem, or the biggest time sink, of building software.

trollbridge · 6 days ago
Astute observation. From where I sit, the market (at least for business software; I am not very familiar with the consumer market) seems to be wide open, and businesses in the 5 - 200 employee range seem to be particularly underserved.

The marketplace for software for single-owner shops or 1-5 employee size places does seem to be quite strong, and then there's enterprise software, but small business seems to have a software marketplace that is atrociously bad. Here is the typical thing a prospective customer asks me to fix for them:

- They are using some piece of software that is essential to their business. - There really isn't much good competition for that software, and it would be a large cost to convert to another platform that also has all the same downsides below. - The software vendor used to be great, but seems to have been sold several times. - The vendor has recently switched to a subscription-only model and keeps on raising subscription prices in the 12% or so range every year, and the cost of this has started to become noticeable in their budget. - They were accustomed to software being a capital investment with a modest ongoing cost for support, but now it's becoming just an expense. - Quality has taken a nosedive and in particular new features are buggy. Promised integrations seem quite lacking and new features/integrations feel bolted on. - Support is difficult to get ahold of, and the formerly good telephone support then got replaced by being asked to open tickets/emails and now has been replaced by an AI chatbot frontend before they can even open a ticket. Most issues go unresolved.

There are literally millions of software packages in existence, and the bulk of them by numbers are niche products used by small businesses. (Think of a software package which solely exists to help you write custom enhancements for another software package which is used by a specific sector of the furniture-manufacturing business, to get an example.) The quality of this sector is not improving.

This is a field that is absolutely ripe for improvement. If the cost of building software really were dropping 90%, this would be a very easy field to move into and simply start offering for $6,000 a year the product that your competition is charging $12,000 a year for, for an inferior product. Before you bring up things like vendor lock-in or the pain of migration... why can't you write software to solve those problems, too? After all, the cost of writing a migration tool should be 90% cheaper now, too, right?
