提供幾個數字做為參考，首先是文章提到的：
Ultimately, Slack was ripe for the taking. Entering 2020 it had lost around 40% of its value since it went public. Consider that after its most recent earnings report, the company lost 16% of its value, and before the Salesforce deal leaked, the company was worth only a few dollars per share more than its direct listing reference price. Toss in net losses of $147.6 million during the two quarters ending July 31, 2020, Slack’s uninspiring public valuation and its winding path to profitability and it was a sitting target for a takeover like this one. The only surprise here is the price.
Slack’s current valuation, according to both Yahoo and Google Finance, is just over $25 billion, which, given its very modest price change after-hours means that the market priced the company somewhat effectively. Slack is up around 48% from its valuation that preceded the deal becoming known.
而 2016 年有新聞說微軟將 Slack 視為價值高達 80 億美元的潛在收購目標。1
The problem is that ARM architecture doesn't clock very high and has high leakage at high power levels (this is also conversely true, x86 is not very good at low power scenarios)
是這樣？ARM 頻率沒辦法撐高嗎？那之後的 M2, M3... 不就...
資源不是無限的啊。
