The Browser Company が #Arc を捨てて新しく作った #Dia 、もうベータ版でたのか。

さて、どんな感じかな…(とりあえず Waitlist に登録した

一応 The Browser Company の名誉のために、実際の記事と文も引用しておくと

> But for most people, Arc was simply too different, with too many new things to learn, for too little reward.

↓【意訳】

> しかし、ほとんどの人にとって Arc はあまりにも(期待と)異なっており、学習コストに対してメリットが少なすぎました。

という部分が、#Arc のユーザーに対して梯子を外す言い回しだな〜と自分が感じたところで、常用はせずともインストールはしていて好意的に見ていた自分としても残念だなと感じた部分でした。

#Arc から #Vivaldi に乗り換えた人の :vivaldi_red: レビュー記事。

The Browser Company の Arc の開発終了の経緯を説明する記事のなかで遠回しに「複雑性を受け入れられる一部のメインストリームではない人たち」みたいに言われた Arc ユーザーの受け皿に :vivaldi_red: がなっている雰囲気を感じる

#Arc が出たとき、自分は掛け値なしに「#Vivaldi の先を行っている!」と感じた部分があったし、自分もそんなに常用はしてなかったけどインストールはしてたし、開発終了が発表される直前までは #Vivaldi とある種の理想を共有する部分があると思ってた。…んだけどな〜

Arc を作ったはずの The Browser Company の Arc への評価が、やっぱり自分は一番残念に感じたのかもな…
どこかで自分はまだ「Arc 、良いブラウザーじゃん!」って思ってるところがあるのかも…それだけに惜しいという気持ちが強い :tony_sigh:

Continued thread

#Vivaldi :vivaldi_red: を 10 年以上使っていると、何年ごしで解決されるバグとか数年前からいまも解決されていない小さなバグとかを見つけることは珍しいことではないんだけど、それでも :vivaldi_red: を使い続ける理由は、Vivaldi 社が :vivaldi_red: を改善しつづけてくれるだろうという信頼感を自分が持ってるからで、その信頼ってある意味いまのプロダクトの機能以上に大事なもののような気がした。

そういう観点で #TheBrowserCompany の CEO の以下の言葉を読むと

> “For most people, Arc was simply too different, with too many new things to learn, for too little reward […] On top of that, Arc lacked cohesion in both its core features and core values. It was experimental, that was part of its charm, but also its complexity,”

> “ほとんどの人にとって、Arc はあまりにも(慣れたブラウザーの操作性と)異なっており、学ぶべき新しいことが多すぎて、それに対する報酬が少なすぎました [...] それに加えて、Arc はその核となっている機能と価値観の両方において一貫性を欠いていました。(Arcは)実験的であり、それは魅力でもあると同時に(デメリットとしての)複雑さがありました」”

これって、内容だけをみれば「まあそういう部分もたしかにあるよね」とは思うけど、 #Arc のユーザーの立場で読むと「それは Arc を作るときからわかっていたのでは?」って感じるし、#Arc の開発をストップする理由としては、なんというか腑に落ちづらい言葉なんじゃないかな…と思った。
まあ、無料でブラウザーを提供し続けるってなかなかできることではないだろうし、 #TheBrowserCompany のビジネスとしての判断もあるのかなーと邪推する部分もあるけど、いまのところは Dia に対する期待よりも Arc の喪失感のほうが大きそう。

なるほど、 #ArcBrowser の開発元の #TheBrowserCompany は Dia という新しい AI ブラウザーの開発をやりたい(というかやっている)、そして #ArcBrowser は売却もしくはオープンソース化が検討されていると。

ただ、その Dia の開発にも使われている技術の一部は #Arc のコードにも含まれていて、それが #Arc のオープンソース化などの障壁になっていて、どうしたもんかなーみたいな状態、ということなのかな。
