Has it become easier to make brilliant moves?

Okay, this may sound like a stupid topic, but I feel like it has become way easier to make so-called "brilliant moves". Remember when brilliant moves used to be this elusive thing that only the best players could make? (slight exaggeration) Now it just feels like brilliant moves are easier to make. I am by no means a good player and have no expectations to have a good game. However, when I just clicked the game review button one day after a random game, it said I had made a brilliant move! I was excited, so I checked which move it was, but I was a bit disheartened when I saw it was a move I thought was obvious which would win the opponent's queen. 

After this game, I thought I would use the game review more often. I made more moves that were classified by the engine as "brilliant". I was just wondering whether the brilliant classification was made to be more lenient. 

Sorry if this was confusing or anything like that. Thanks.

Brilliant moves are just ones that sacrifice material or allow material to be captured and are best or good. In some positions, it would be easier to them than others.

The definition was changed in October 2021:

Brilliant (!!) moves and Great Moves are always the best or nearly best move in the position, but are also special in some way.We replaced the old Brilliant algorithm with a simpler definition: a Brilliant move is when you find a good piece sacrifice.There are some other conditions, like you should not be in a bad position after a Brilliant move and you should not be completely winning even if you had not found the move. Also, we are more generous in defining a piece sacrifice for newer players, compared with those who are higher rated.

Thank you, that makes sense. 

Question: From the statement above, if the position is equal and you made a move including a sacrifice but is also the best move: Is it considered a brilliant move?

If the answer to the question is yes: then, Is it right to say that you can find many brilliant moves in a game that the evaluation fluctuates a lot from equal to winning?

If these is the case: does it mean that there is high possibility that you can find also many blunders in the game because of this evaluation fluctuation?

If all of the answer on the above is true: Can we still be happy if there are many brilliant move in our game?

there is no such thing as a brilliant move

Best move is the best move an 18 ply (9 turns of future plays) AI could find. Brilliant move is a move that results better than the best move.
