Brief

swyx recounts following CUA from World of Bits (2017) through Adept/@jluan, Anthropic's Computer Use launch, Claude Cowork, and a recent ai:dot engineer track—and asserts GPT-5.6+Superapp now surpasses those systems. He has his nontechnical staff using CUA for real administrative workflows and warns that underestimating current capabilities (he critiques one take by Dwarkesh) is dangerous for AI decision-making.

Why it matters

@swyx claims GPT-5.6 + Superapp now outperforms prior CUA efforts he tracked: World of Bits (Shi et al. 2017), Adept/@jluan (interview ~3 years ago), Anthropic's Computer Use launch (~2 years ago), Claude Cowork (~3 months ago), and a full CUA track at @aidotengineer (3 weeks ago).

Key details

  • He instructed his nontechnical team to use CUA for real knowledge‑work: signing up for payment and invoicing portals and handling speaker/sponsor/attendee/vendor/union data requests, asserting these tools are already fast and practical for everyday workflows.
  • He warns that anyone who agrees with a criticized take (he names Dwarkesh) is 'so not up to date' and that underestimating CUA capabilities is a 'dangerous category error' for AI decision‑making; he stresses this is a critique of one take, not of Dwarkesh personally.
Source evidence

someone just told me about this take* on CUA

this is one of those gell mann moments for me lol. i've been watching computer use since World of Bits (Shi, fan, karpathy, hernandez & liang 2017). we were the first technical pod to interview @jluan about Adept's work three years ago, we were there in the @AnthropicAI building when they first launched Computer Use 2 years ago, I fanboyed over Claude Cowork in our @felixrieseberg pod 3 months ago, and we ran our first full computer use track at @aidotengineer ft. @DhruvBatra_ @proceduralia @francedot 3 weeks ago.

GPT 5.6 + Superapp is even better at CUA than everything i just mentioned. excited for our @AriX podcast to discuss the @skybysoftware story and Codex progress.

if you actually use these things as intensely as we do, CUA is progressing so, so incredibly fast. i have asked my nontechnical team to CUA as much as possible, all their knowledge work with signing up for random payment and invoicing portals and speaker and sponsor and attendee and vendor and union data requests. if you found yourself nodding along to this take below, you are so not up to date that you don't know what you don't know, and underestimating capabilities is quite a dangerous category error if you are doing any ai decisionmaking.

*i admire dwarkesh alot; only criticizing one single take, not the message nor the overall enterprise, screenshot only to share
