HBO?s tech industry comedy 'Silicon Valley' begins season 5 next month. A brand new trailer offers a better idea of what viewers can look forward to. There will be plenty of changes in the new season. The biggest change will be the absence of T.J. Miller?s Erlich Bachman. Miller announced his departure long before any accusations of sexual assault were levied against him. In season 5, the Pied Piper team will institute its new internet.
