The 10 Inventions of Nikola Tesla That Changed The World
The modern world was we know it wouldn't exist without Telsa. Those other guys you quote were greats as well. A person really needs to go and read up
on these guys to make up their own mind. In my opinion Telsa was head and shoulders above all.

OK, let's go through that list.
1. Alternatiing Current. No Tesla did not invent alternating current. He invented an improved system of generation and transmission with three
phases which permitted more economical transmission than a single or two phase system equivalent because it uses less physical conductor given voltage
Three phase power was, according to Wikipedia invented simultaneously by Tesla and 2 others (independently) in the late 1880's.
2. Flourescent bulbs - No the effect was known. It was other people who actually put forth the engineering work to make flourescent bulbs a
3. Xrays. Site said "X-rays, like so many of Tesla's contributions, stemmed from his belief that everything we need to understand the universe is
virtually around us at all times, but we need to use our minds to develop real-world devices to augment our innate perception of existence." WTF?
As far as I know, Tesla didn't do very much at all with X-rays, certainly nothing really useful or important like X-ray crystallography.
4. Radio. Technologies for early radio were invented by a number of people. David Hughes had some early inconclusive success, then rightly Heinrich
Hertz was credited with the first rigorous confirmation of electromagnetic waves experimentally, with clear transmitter and receiver. He however was
doing this as basic science not engineering. After this was demonstrated as physical phenomenon the race was on with many people attempting to make
radio practical. Tesla played an important role with a more practical system, the main contribution being high frequency oscillation. But there were
many people involved in the beginning, more than only Marconi and Tesla. en.wikipedia.org...
It was the use of vacuum
tubes (not by Tesla) which really made radio practical.
5. Remote control - yes, if you have radio you have remote control. He was not the only one to recognize and implement this.
6. electric motor- This goes with the 3 phase system. He did not invent the electric motor (Faraday did) but one particular form of multi-phase AC
induction motor which became very important in the Westinghouse system.
7. robotics - no.
8. laser - no way. Einstein invented the theory and the concept. It wasn't experimentally done for decades later. Tesla didn't understand or believe
quantum mechanics and lasers work only with quantum mechanics.
9. wireless communication and limitless free energy - wireless communication is radio, and there is no limitless free energy.
Coming back to reality, Tesla invented and managed to commercialize a practical three phase transmission and generation system which is his most
important invention. He also did significant work in early radio, but he was one of a number, and his system did not become commercially practical.
There's a false believe that Tesla had some ultra-advanced esoteric knowledge that others didn't. Isn't true. He was important (until he turned nuts)
in the early phases of the most important period for development of electric and electronic technology, but there were thousands of people involved as
well. After the 1920's Tesla was behind the state of the art in understanding in engineering and science (superheterodyne radio + quantum mechanics).
