请教一下巨硬 office 队伍的朋友

组里老大问我喜欢做什么方面的工作，我也搞不太清楚office现在哪个方面发展更好一些，我只说偏向service和cloud
这是老大说
"
We do services work on the team as well as client, but all developers on the team are full stack developers, so you would be doing a mix of client and services work if you worked on one of the teams that does service (not all my teams do). There are 2 teams that do both client and service work:
OArt Platform: which is the graphics platform for all Office graphics rendering. This team owns the scene graph, canvas interaction, Graphics Objects and features, Picture Auto-Caption service, and some Ink Service integration.

Pen and Ink Team: develops the digital pen and ink features and Ink Analysis Service (Ink-to-text, Ink-to-Shape, Ink-to-Math Conversion)"

看得我一头雾水，我听朋友说，现在微软做service好像意义不大，我的最终目的是回国发展的，想请教一下大家，我该选什么方向呢

要不要去知乎问问轮子哥....
