Dalam ranah pascahumanisme dalam filsafat teknologi. Eksistensialisme seringkali dianggap tidak penting. Hal ini dikarenakan, dalam pencarian filsafat teknologi pemaknaan manusia terhadap teknologi sering dianggap antroposentris. Namun, sejatinya perenungan eksistensialisme tersendiri justru penting agar seorang engineer melakukan refleksi diri dan mempunyai penjiwaan atas apa yang ia sedang rancang, rakit, ataupun buat. Terkhususnya dalam welding engineering process yang merupakan ranah engineering dengan tingkat kesulitan yang tinggi. Jika refleksi diri dan penjiwaan dalam perancangan, perakitan, dan pembuatan artefak engineering ini dikesampingan dan tidak dibahas. Maka artefak dan teknologi tetap hanya dinilai sebagai instrumen ataupun objek belaka yang tidak memiliki creative energy untuk membuat menampakkan sesuatu. Pada kesempatan inilah relasi I-Thou yang di rancang oleh Martin Buber dapat membantu seorang engineer menampakkan state of the art dari artefak dengan dialog bersama teknologi yang menghasilkan creative energy bersama yang aktif.

In the realm of post-humanism on philosophy of technology, Existentialism is often deemed unimportant. This is because in philosophy of technology, humans meaning of technology is often considered anthropocentric. However, in fact, independent existentialist contemplation is actually important so that an engineer can self-reflect and have an understanding of what he/she is designing, assembling or creating. Especially in the welding engineering process, which is an engineering domain with a high level of difficulty. If self-reflection and spirit in the design, assembly and manufacture of engineering artifacts are sidelined and not discussed. So artifacts and technology are still only valued as mere instruments or objects that do not have the creative energy to do something. It is on this occasion that the I-Thou relationship designed by Martin Buber can help an engineer reveal the state of the art of artifacts through dialogue with technology that produces active joint creative energy.
