Imagination
I think imagination is an important factor for humans to grow. especially in technology. Believe me or not I think Imagination is more important than reality too!!! just think about it. When you are watching my content you are definitely using your PC or mobile. these tools weren't available in the past or were very big. big expensive computers in past are now in every home. what about cars? or airplanes or walking on the moon?!!! Your mind is so powerful.it can make your dreams come true. we are using tools that people wanted to use in the past and future generations will use new technologies that we dream about. ok, you may already know all of these things but let me show you some pictures to understand these huge improvements better.

1-cellphones before and now


A DynaTAC 8000X; the first commercially available mobile phone from 1983

DynaTAC is a series of cellular telephones manufactured by Motorola, Inc. from 1983 to 1994. The Motorola DynaTAC 8000X commercial portable cellular phone received approval from the U.S. FCC on September 21, 1983.[1] A full charge took roughly 10 hours, and it offered 30 minutes of talk time.[2] It also offered an LED display for dialing or recall of one of 30 phone numbers. It was priced at $3,995 in 1984, its commercial release year, equivalent to $9,952 in 2020.[3] DynaTAC was an abbreviation of "Dynamic Adaptive Total Area Coverage."(Wikipedia)

Just look at the price. $3995 dollars for this big cellphone with just 30 minutes of talk time. Thanks to technology you shouldn't really pay this amount of money now. actually, you can buy high-end cellphones under 1500$ that have decent cameras, gaming capability, and fits in your pocket!!!

2-Computers before and after


The UNIVAC I (UNIVersal Automatic Computer I) was the first general-purpose electronic digital computer design for business application produced in the United States.[1] It was designed principally by J. Presper Eckert and John Mauchly, the inventors of the ENIAC. Design work was started by their company, Eckert–Mauchly Computer Corporation (EMCC), and was completed after the company had been acquired by Remington Rand (which later became part of Sperry, now Unisys). In the years before successor models of the UNIVAC I appeared, the machine was simply known as "the UNIVAC".[2] (Wikipedia)

I know that this computer looks really nice but It is clear that it was too big to work with it even in the offices!!!

Personal computers came out:


Commodore PET in 1983 (at the American Museum of Science and Energy), an early example of a personal computer(Wikipedia)

The three personal computers referred to by Byte Magazine as the "1977 Trinity" of home computing: The Commodore PET, the Apple II, and the TRS-80 Model I. (Wikipedia)
now we have this:

If you ask your grandmother she will tell you how amazing TVs were in the past. this magic invention has changed people's lifestyle, thinking, and...
probably in both positive and negative ways!!!

I am super excited to see what will happen in the future. I hope there will be a no-charged phone. it looks impossible but I believe the impossible will be possible in the future.
