  1. ​ @nicklikesradio  Govt is a corrupted, overspending, bureaucratic mess, but not necessarily evil. Military black projects may or may not be evil. ​ @TimeWalker Electric cars do not use nonrechargeable batteries. Might actually be more practical than gas, from a design and manufacturability standpoint, as you don't have to deal with an engine and a driveshaft.

  2. Yes. We now put billions of them in a chip with a surface area of less than 1 square inch.

  3. Earth will be without life due to radiation. (Global Thermonuclear War)

  4. Only panel switches had motors.

  5. Indeed. "You're breaking up!" wasn't a thing back then because the telephones didn't send data in packets. The system used a dedicated circuit for each call. The quality then was higher than it is today on most trinks. The downside was that telephone lines couldn't carry as many calls per wire, the switching systems were big, power hungry, and easy to hack, and the other party might be barely audible on the other end of a long line.

  6. I once found an old 35mm slide projector in the back closet of my school.

  7.  D B  They didn't have encryption of any kind, although texting was a thing, as long as both parties had teletype machines.

  8. The problem would be in that box, not the phone network.

  9. Imagine 2020 compared to 946

  10. They were so focused on the telephone network that they could not predict IP, servers, or packet switching.

  11. No reason to.

  12. maybe about 20.

  13. You want the military to maintain the telephone network?

  14. 2600 Hz would be sent down a trunk when it was idle.

  15. It costed extra because it required extra equipment in the central office. 3 way calling bridges are not cheap! Also, this did not become common until the 80s due to older systems already being in place.

  16.  @bongiovi7618  It definitely will not, as it has no GPU. It would still take several warehouses full of tube based equipment to match it in terms of FLOPS.

  17. We still can't.

  18. Cell networks are entirely digital.

  19.  49jubilee  Agreed. It wouldn't have been the same. There would be no DNS or HTTP. There would be data phones.

  20. Those require transistors to run, and LEDs are a type of diode.

  21. The 486 is certainly not the first microprocessor, but the IBM PC was the most successful computer and remains the standard to this day.

  22. 7 digits. They just chose to write the first 2 as letters.

  23. This film was created in the middle of the civil rights movement.

  24. Don't forget RTX graphics.

  25.  @cesaranthonyviralta5495  If the elevator kept moving, I would assume it was a mechanical failure in the door causing it become detached from the motor. The alternative is a major problem with the controller which resulted in the door opening and the safety circuit having no effect.

  26. Actually more computer than telephone.

  27. Unfortunately, this does not apply to rural ISPs. When the ISP's facility burns down the ISP goes out of business, some towns will have no internet whatsoever for 5 years or more, as the local town councils only allow one ISP to have service in their town, and changing the allowed ISP is a big slow process that involves lots of bureaucratic red tape.

  28. I guess they never foresaw the invention of the integrated circuit or the microprocessor.

  29. Aliens would have destroyed the craft rather than let it crash on a planet with such a barbaric society.

  30.  @gertraba4484  How is an interstellar exploration ship going to be affected by something as simple as lightning? Even our own relatively primitive Starships aren't affected by lightning. Also, why would they be in the lower atmosphere in the first place? If I owned a ship, I wouldn't even want to go into a low orbit because of the potential for spy satellites or orbital weapons platforms.

  31. Maybe, but they may just use really fast microprocessors in the future.

  32. Was the only economical option for rural areas and PABXs.

  33. And phones will no longer ring indefinitely. Also, any modern phone will immediately disconnect if the line is busy.

  34. This video demonstrates ESS, which should be natively DTMF, therefore requiring no extra equipment.
    1
  35. There are automated bots that dislike videos on YouTube.

  36. This probably worked using a small rotary switch attached to the phone line, rather than running 10 phone lines to each subscriber.

  37. The lines and equipment were expensive.

  38. CDMA is entirely digital. Neither pulse nor tone is used.

  39. Anyone can ring the bell.

  40. Switchboards!

  41. 1ESS can't do that unless it's done manually by the telephone man. Also, this switch isn't Chinese or North Korean.

  42. This guy played Captain Kirk in the original series of Star Trek.

  43. Did step even have direct distance dialing? It may have just sent the call directly to a long-distance tandem when you dial 1.

  44. Because you are looking for the number 53.

  45. Unfunny joke about the computer on the Enterprise, which was outdated when new.

  46. By drawing it by hand, and then scanning it onto film.

  47. If they found a crashed ship, we would have had a lot more "inventions" than rudimentary transistors. The transistor was discovered during a study on semiconductors.

  48. Yes, due to the very long telephone lines connected to the system, but likely repairable.

  49. "nutcase conspiracists like you" Who is this referring to?

  50. Why not?
