+      On its face, bpftrace is a simple DSL/tracing-tool for writing BPF programs.
+      It abstracts away a lot of the complicated user and kernel space code
+      neccessary to write observability and debugging programs.
+      However, adding new language features/syntax isn't easy.
+      There are a lot of considerations to be made in regards to bpftrace's primary
+      usecases and the classic problem of how much complexity/details to hide from the user.
+      This talk will explore some recent case studies (e.g. adding "let")
+      and discuss some of the challenges of evolving this DSL.

+      <p>For many years, firewall solutions on Linux have grown and evolved,
+      without any major change, until eBPF.
+      While eBPF can allow very fast and efficient packet filtering,
+      the learning curve doesn't make it easily accessible to non-developers.
+      bpfilter aims to bridge the gap between existing tools (nftables, iptables)
+      and modern technologies such as eBPF.</p>
+      <p>By translating filtering rules into native code, bpfilter abstracts the
+      complexity behind cutting-edge kernel technologies while maintaining backward
+      compatibility with existing solutions. Let's discuss about bpfilter and see it in action!</p>
