> but then again if you'd showed me an RPi5 back in 1977 I would have said "nah, impossible" so who knows? I was reading lots of scifi in 1977, so I may have tried to talk to the pi like Scotty trying to talk to the mouse in Star Trek IV. And since you can run an LLM and text to speech on an RPi5, it might have answered.

Someday real soon, kids being shown episodes of 'Knight Rider' by their grandparents won't understand why a talking car was so futuristic.

It’s impossible to explain to kids now why it was funny on Seinfeld when Kramer pretended to be MoviePhone and says “why don’t you just tell me the name of the movie you selected!”

> Someday real soon, kids being shown episodes of 'Knight Rider' by their grandparents won't understand why a talking car was so futuristic. Maybe in 100 years. The talking car was more intelligent than Siri, Alexa or Hey Google. It is not that we are not able to "talk" to computers, it is that we "talk" with computers only so that they can collect more data about us. Their "intelligence" is limited to simple text un…

I think maybe you missed the last three years. We're not talking about Alexa or Hey Google level.

We're talking about Google Gemini or ChatGPT.

Like James Bond's Aston Martin with a satnav/tracking device in 1964's Goldfinger. Kids would know what that was but they might not understand why Bond had to continually shift some sort of stick to change the car's gear.

Gear shifting it's still a thing in Europe, and mandatory if you want to get your driver's license.

Not really. My 1983 Datsun would talk, but it couldn't converse. Alexa and Siri couldn't hold a conversation anywhere near the level KITT did. There's a big difference. With LLMs, we're getting close.

Commodore 64 had text to speech in late 80s. Also, my friend's father in the 80s was the driver of a French Consulate's member in Turkey. His car (a Renault) had speech functionality.

Test to speech it's trivial with Dr. Sbaitso or Flite in ARMv5/Pentium 90 machines.

you can get a driver license with an automatic. But it just means you can only drive automatics.

It would have been a huge deal not being able to drive manuals 20y ago but hybrid and ev all being automatic it is not that much of a downside nowadays unless you want to buy old cars or borrow friend's car. Most renting fleets have autos available nowadays.

It is a frequent fantasy of mine to bring tech back to historical figures, like to show my phone to Galileo or to take Leonardo da Vinci for a ride in my car. But I guess you don't need to go that far to blow minds.

Just show it to someone being released after 30 to 40 years in jail.

I guess I'm old because this hasn't really been that insightful of interesting observation just by itself anymore. People often talk about technological advancement of computing as if it is a force of nature whereas the amazing specs of say a rp2350 compared to the cray-1 is more of a story of the economies of scale as opposed to merely technical know-how and design. The reason a rp2350 is a few dollars is because of…

I think the really interesting post here is that a reasonably high level of computer is basically free. you can get a 32 but microcontroller with 16mb of ram at above 100mhz for well under $1. you can buy a USB cable and it has 2 full computers inside it.

What I find somewhat puzzling is that these machines were used for the "really big problems". We used supercomputers for weather forecasting, finite element simulations, molecular modeling. And we were getting results. I don't feel we are getting results that are thousands of times better today.

We aren't getting results thanks of times better. we're getting results 10s of times better on problems with cubic (or worse) scaling. e.g. 3 day forecasts as of 2017 are more reliable than 1 day forecasts in 1990 https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2F...

Hardware has gone a long way... ...software... well, that's a different story. While a cray could compute millions of things and did a bunch of usable stuff for many groups of people who used it back then, a raspberrypi today has trouble even properly displaying a weather forecast at "acceptable speeds", because modern software has become very bloated, and that includes weather forecast sites that somehow have to inc…

otoh a pi running stockfish would beat deep blue 100-0
