On January 28, Tesla announced R & D spending of 39 in 2023.$6.9 billion, a company record high, but still well below some of the other tech companies in the Big Seven。It is reported that Apple invested as much as 299 in fiscal year 2023..$200 million for R & D, Microsoft's R & D spending also reached $27.2 billion。Sawyer Merritt, an electric car analyst, posted on X: "Apple spent about $29 billion on research and development in 2023, more than the total amount spent on research and development in Tesla's history.。It really shows you how much innovation Tesla gets for every dollar invested in R & D.。Tesla CEO Elon Musk responded: "There are huge differences between companies in terms of the effectiveness of R & D spending.。"

Recently, a blogger posted a news screenshot on the social platform, showing that Apple invested 262 in 2022.$500 million for R & D。However, this screenshot is not meant to praise Apple, as another screenshot shows that the standard iPhone 15 model is only 1g lighter than the iPhone 14。These two screenshots combine to suggest that Apple's R & D costs are "not commensurate" with the final output.。Hours later, Tesla CEO Musk replied below the tweet that "the price / performance ratio does not seem to be high."。Judging from Musk's reply, he also felt the same way about Apple's huge investment in research and development but not very effective, and issued a complaint.。
