English (translated by GPT-4):

To AWTF2022 Contestants,

Thank you so much for participating in the contest. I apologize for not being able to communicate much due to my inability to speak English. Did you enjoy the contest event? I look forward to seeing you again in Japan.

To Everyone,

With the conclusion of the topcoder open (TCO) and Google Code Jam (GCJ), and the decision to hold Meta Hacker Cup 2023 online, the only on-site contest in 2023 where anyone from around the world can participate and truly determine the world's best is the AtCoder World Tour Finals.

I have participated in the topcoder open finals 5 times (Marathon division) and in the Google Code Jam finals once. Both tournaments were outstanding. From my experience as a competitive programmer, participating in these competitions has been significant, and I believe that this culture must continue.

The AtCoder World Tour Finals is a budding event. Compared to TCO and GCJ, it has a shorter history, and there are many novice aspects in its management. However, I believe that the level of participants and the quality of problems presented are on par with these events. This is thanks to those managing AtCoder problems, like maroonrk and rng_58, and the problem setters who support them. I am confident that we will continue to provide high-quality problems in the future. I hope that someday, AWTF can grow to be valued as much as, if not more than, TCO and GCJ.

Currently, AtCoder Corporation only has revenue from within Japan. The AtCoder Grand Contest and World Tour Finals operate as charitable activities and are running at a loss. We don't see a clear profit path for the future, but we intend to continue these ventures as much as possible. If you have any ideas or suggestions, we might ask for your assistance in the future.

Thank you for your continued support of AtCoder.

Japanese:

本戦参加者の方へ

コンテストに参加していただき、誠にありがとうございます。僕が全く英語を話せないせいで、あまり交流が出来ず申し訳ありません。コンテストイベントは楽しんで頂けましたでしょうか?また日本でお会いできる日を楽しみにしています。

全ての方へ topcoder open(TCO)やGoogle Code Jam(GCJ)の開催終了が決定し、Meta Hacker Cup 2023のオンライン開催も決まり、世界の誰がも参加でき、名実ともに世界一を決める2023年のオンサイトコンテストは、AtCoder World Tour Finalsだけとなってしまいました。

僕は、topcoder openの決勝に5回(Marathon部門)、Google Code Jamの決勝に1回参加していますが、どちらの大会も素晴らしいものでした。選手として競技プログラミングに取り組む上で、これらの大会に出場した経験は大きく、この文化を絶やすわけにはいかないと考えています。

AtCoder World Tour Finalsは、新興イベントです。TCOやGCJと比べ歴史が浅く、イベント運営に関しても稚拙な点が多くあります。ですが、参加者のレベルや、出題している問題については、これらのイベントと遜色ないものを提供出来ているのではないかと考えています。これらはAtCoderの問題を管理している maroonrkrng_58 、それらを支える作問者のお陰であり、今後も継続してクオリティの高い問題を提供し続けられる自信があります。いつかAWTFをTCOやGCJと同等以上の価値を感じられるイベントに成長できたらと思っています。

現在、AtCoder株式会社は、日本国内からしか売上がありません。AtCoder Grand ContestやWorld Tour Finalsは慈善事業となっており、赤字を垂れ流している状態です。今後も収益の目途は立っていないのですが、可能な限りこれらの事業は続けたいと考えています。何かアイデアが浮かびましたら、今後何かのご協力をお願いすることがあるかもしれません。

今後ともAtCoderをよろしくお願いいたします。
