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.。
