00:02:22I think that computers are the most powerful tool ever created by humanity.

00:04:14…the computer is a creative tool and a creative process that's not gonna be automated away.

00:10:34So I think it's completely fine to use an entrepreneur as a source of inspiration, but I think it's silly to use them as a source of truth.

00:18:52…you wanna be rich and anonymous, not poor and famous.

00:20:49So I just decided, five or six years ago, that I was done being miserable and I was gonna be happy…

00:22:07…part of being happy is not caring what other people think and so I don't care anymore.

Know what each result means

Have an audio recording instead?

Sign in to upload MP3, M4A, WAV, FLAC or other common audio, or choose an MP4 or MOV video: the page extracts the audio track on your device and uploads only the sound. Audio files are limited to 60 MiB; AAC M4A and extracted tracks at an average of 320 kbps or less follow the duration limit instead. Free allowances, S and Single Pass allow up to 120 minutes; valid Pack L credits support up to 180 minutes, with enough L transcription minutes required for the full task. Check your available transcription minutes and audio-processing notice before confirming. Uploading alone does not start transcription. The resulting text is restricted to your account. A transcribed local upload can use automatic speaker detection while its original is within the retention window (around six hours after upload); the original audio cannot be played back after it is deleted.
